The Lyα emitter (LAE) fraction, XLAE, is a potentially powerful probe of the evolution of the intergalactic neutral hydrogen gas fraction. However, uncertainties in the measurement of XLAE are still under debate.\r\nAims. Thanks to deep data obtained with the integral field spectrograph Multi Unit Spectroscopic Explorer (MUSE), we can measure the evolution of the LAE fraction homogeneously over a wide redshift range of z ≈ 3–6 for UV-faint galaxies (down to UV magnitudes of M1500 ≈ −17.75). This is a significantly fainter range than in former studies (M1500 ≤ −18.75) and it allows us to probe the bulk of the population of high-redshift star-forming galaxies.\r\nMethods. We constructed a UV-complete photometric-redshift sample following UV luminosity functions and measured the Lyα emission with MUSE using the latest (second) data release from the MUSE Hubble Ultra Deep Field Survey.\r\nResults. We derived the redshift evolution of XLAE for M1500 ∈ [ − 21.75; −17.75] for the first time with a equivalent width range EW(Lyα) ≥ 65 Å and found low values of XLAE ≲ 30% at z ≲ 6. The best-fit linear relation is XLAE = 0.07+0.06−0.03z − 0.22+0.12−0.24. For M1500 ∈ [ − 20.25; −18.75] and EW(Lyα) ≥ 25 Å, our XLAE values are consistent with those in the literature within 1σ at z ≲ 5, but our median values are systematically lower than reported values over the whole redshift range. In addition, we do not find a significant dependence of XLAE on M1500 for EW(Lyα) ≥ 50 Å at z ≈ 3–4, in contrast with previous work. The differences in XLAE mainly arise from selection biases for Lyman Break Galaxies (LBGs) in the literature: UV-faint LBGs are more easily selected if they have strong Lyα emission, hence XLAE is biased towards higher values when those samples are used.\r\nConclusions. Our results suggest either a lower increase of XLAE towards z ≈ 6 than previously suggested, or even a turnover of XLAE at z ≈ 5.5, which may be the signature of a late or patchy reionization process. We compared our results with predictions from a cosmological galaxy evolution model. We find that a model with a bursty star formation (SF) can reproduce our observed LAE fractions much better than models where SF is a smooth function of time.","lang":"eng"}],"publication":"Astronomy & Astrophysics","article_processing_charge":"No","article_number":"A12","language":[{"iso":"eng"}],"status":"public","extern":"1","oa_version":"Published Version","oa":1,"year":"2020","publication_status":"published","publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"date_published":"2020-06-03T00:00:00Z","publisher":"EDP Sciences","quality_controlled":"1","month":"06","day":"03","intvolume":" 638","arxiv":1,"citation":{"ista":"Kusakabe H, Blaizot J, Garel T, Verhamme A, Bacon R, Richard J, Hashimoto T, Inami H, Conseil S, Guiderdoni B, Drake AB, Christian Herenz E, Schaye J, Oesch P, Matthee JJ, Anna Marino R, Borello Schmidt K, Pelló R, Maseda M, Leclercq F, Kerutt J, Mahler G. 2020.

Our resolved spectroscopic analysis of the LAHs reveals significant intrahalo variations of the Lyα line profile. Using a three-dimensional two-component model for the Lyα emission, we measured the full width at half maximum (FWHM), the peak velocity shift, and the asymmetry of the Lyα line in the core and in the halo of 19 galaxies. We find that the Lyα line shape is statistically different in the halo compared to the core (in terms of width, peak wavelength, and asymmetry) for ≈40% of our galaxies. Similarly to object-by-object based studies and a recent resolved study using lensing, we find a correlation between the peak velocity shift and the width of the Lyα line both at the interstellar and circum-galactic scales. This trend has been predicted by radiative transfer simulations of galactic winds as a result of resonant scattering in outflows. While there is a lack of correlation between the spectral properties and the spatial scale lengths of our LAHs, we find a correlation between the width of the line in the LAH and the halo flux fraction. Interestingly, UV bright galaxies (MUV < −20) show broader, more redshifted, and less asymmetric Lyα lines in their haloes. The most significant correlation found is for the FWHM of the line and the UV continuum slope of the galaxy, suggesting that the redder galaxies have broader Lyα lines. The generally broad and red line shapes found in the halo component suggest that the Lyα haloes are powered either by scattering processes through an outflowing medium, fluorescent emission from outflowing cold clumps of gas, or a mix of both. Considering the large diversity of the Lyα line profiles observed in our sample and the lack of strong correlation, the interpretation of our results is still broadly open and underlines the need for realistic spatially resolved models of the LAHs."}],"article_number":"A82","language":[{"iso":"eng"}],"article_processing_charge":"No","oa":1,"extern":"1","status":"public","oa_version":"Published Version","date_published":"2020-03-11T00:00:00Z","publication_status":"published","year":"2020","publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"publisher":"EDP Sciences","quality_controlled":"1"},{"abstract":[{"lang":"eng","text":"We report the spectroscopic confirmation of a new protocluster in the COSMOS field at z ∼ 2.2, COSMOS Cluster 2.2 (CC2.2), originally identified as an overdensity of narrowband selected Hα emitting candidates. With only two masks of Keck/MOSFIRE near-IR spectroscopy in both H (∼1.47–1.81 μm) and K (∼1.92–2.40 μm) bands (∼1.5 hr each), we confirm 35 unique protocluster members with at least two emission lines detected with S/N > 3. Combined with 12 extra members from the zCOSMOS-deep spectroscopic survey (47 in total), we estimate a mean redshift and a line-of-sight velocity dispersion of zmean = 2.23224 ± 0.00101 and σlos = 645 ± 69 km s−1 for this protocluster, respectively. Assuming virialization and spherical symmetry for the system, we estimate a total mass of Mvir ∼ (1–2) ×1014M⊙ for the structure. We evaluate a number density enhancement of δg ∼ 7 for this system and we argue that the structure is likely not fully virialized at z ∼ 2.2. However, in a spherical collapse model, δg is expected to grow to a linear matter enhancement of ∼1.9 by z = 0, exceeding the collapse threshold of 1.69, and leading to a fully collapsed and virialized Coma-type structure with a total mass of Mdyn(z = 0) ∼ 9.2 × 1014M⊙ by now. This observationally efficient confirmation suggests that large narrowband emission-line galaxy surveys, when combined with ancillary photometric data, can be used to effectively trace the large-scale structure and protoclusters at a time when they are mostly dominated by star-forming galaxies."}],"publication":"The Astrophysical Journal","doi":"10.3847/1538-4357/ab75c3","title":"Spectroscopic confirmation of a coma cluster progenitor at z ∼ 2.2","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2002.06207"}],"quality_controlled":"1","publisher":"IOP Publishing","publication_status":"published","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"year":"2020","date_published":"2020-03-19T00:00:00Z","oa_version":"Preprint","extern":"1","status":"public","oa":1,"article_processing_charge":"No","language":[{"iso":"eng"}],"article_number":"8","external_id":{"arxiv":["2002.06207"]},"citation":{"ieee":"B.

Here, we measure the average velocity offset for a sample of 96 z ≈ 3.3 Ly α emitters (LAEs) with a median Ly α flux (luminosity) of ≈10−17 erg cm−2 s−1 (≈1042 erg s−1) and a median star formation rate (SFR) of ≈1.3 M⊙ yr−1 (not corrected for possible dust extinction), detected by the Multi-Unit Spectroscopic Explorer as part of our MUSEQuBES circumgalactic medium (CGM) survey. By postulating that the stacked CGM absorption profiles of these LAEs, probed by eight background quasars, must be centred on the systemic redshift, we measure an average velocity offset, Voffset = 171\\pm 8 km s−1, between the Ly α emission peak and the systemic redshift. The observed Voffset is lower by factors of ≈1.4 and ≈2.6 compared to the velocity offsets measured for narrow-band-selected LAEs and Lyman break galaxies, respectively, which probe galaxies with higher masses and SFRs. Consistent with earlier studies based on direct measurements for individual objects, we find that the Voffset is correlated with the full width at half-maximum of the red peak of the Ly α line, and anticorrelated with the rest-frame equivalent width. Moreover, we find that Voffset is correlated with SFR with a sub-linear scaling relation, Voffset∝SFR0.16±0.03. Adopting the mass scaling for main-sequence galaxies, such a relation suggests that Voffset scales with the circular velocity of the dark matter haloes hosting the LAEs."}],"publication":"Monthly Notices of the Royal Astronomical Society","article_processing_charge":"No","related_material":{"link":[{"url":"https://doi.org/10.1093/mnras/staa2668","relation":"erratum"}]},"language":[{"iso":"eng"}],"extern":"1","status":"public","oa_version":"Preprint","oa":1,"year":"2020","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"publication_status":"published","date_published":"2020-08-01T00:00:00Z","publisher":"Oxford University Press","quality_controlled":"1","page":"1013-1022"},{"quality_controlled":"1","publisher":"Oxford University Press","page":"3043-3059","publication_status":"published","year":"2020","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"date_published":"2020-10-01T00:00:00Z","oa_version":"Preprint","status":"public","extern":"1","oa":1,"article_processing_charge":"No","language":[{"iso":"eng"}],"abstract":[{"text":"CR7 is among the most luminous Ly α emitters (LAEs) known at z = 6.6 and consists of at least three UV components that are surrounded by Ly α emission. Previous studies have suggested that it may host an extreme ionizing source. Here, we present deep integral field spectroscopy of CR7 with VLT/Multi Unit Spectroscopic Explorer (MUSE). We measure extended emission with a similar halo scale length as typical LAEs at z ≈ 5. CR7’s Ly α halo is clearly elongated along the direction connecting the multiple components, likely tracing the underlying gas distribution. The Ly α emission originates almost exclusively from the brightest UV component, but we also identify a faint kinematically distinct Ly α emitting region nearby a fainter component. Combined with new near-infrared data, the MUSE data show that the rest-frame Ly α equivalent width (EW) is ≈100 Å. This is a factor 4 higher than the EW measured in low-redshift analogues with carefully matched Ly α profiles (and thus arguably H I column density), but this EW can plausibly be explained by star formation. Alternative scenarios requiring active galactic nucleus (AGN) powering are also disfavoured by the narrower and steeper Ly α spectrum and much smaller IR to UV ratio compared to obscured AGN in other Ly α blobs. CR7’s Ly α emission, while extremely luminous, resembles the emission in more common LAEs at lower redshifts very well and is likely powered by a young metal-poor starburst.","lang":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","doi":"10.1093/mnras/staa2550","title":"The nature of CR7 revealed with MUSE: A young starburst powering extended Ly α emission at z = 6.6","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2008.01731"}],"author":[{"last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J"},{"last_name":"Pezzulli","first_name":"Gabriele","full_name":"Pezzulli, Gabriele"},{"full_name":"Mackenzie, Ruari","last_name":"Mackenzie","first_name":"Ruari"},{"full_name":"Cantalupo, Sebastiano","first_name":"Sebastiano","last_name":"Cantalupo"},{"full_name":"Kusakabe, Haruka","last_name":"Kusakabe","first_name":"Haruka"},{"first_name":"Floriane","last_name":"Leclercq","full_name":"Leclercq, Floriane"},{"full_name":"Sobral, David","last_name":"Sobral","first_name":"David"},{"full_name":"Richard, Johan","last_name":"Richard","first_name":"Johan"},{"full_name":"Wisotzki, Lutz","first_name":"Lutz","last_name":"Wisotzki"},{"full_name":"Lilly, Simon","first_name":"Simon","last_name":"Lilly"},{"full_name":"Boogaard, Leindert","last_name":"Boogaard","first_name":"Leindert"},{"first_name":"Raffaella","last_name":"Marino","full_name":"Marino, Raffaella"},{"first_name":"Michael","last_name":"Maseda","full_name":"Maseda, Michael"},{"last_name":"Nanayakkara","first_name":"Themiya","full_name":"Nanayakkara, Themiya"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: evolution","galaxies: high-redshift","dark ages","reionization","first stars","cosmology: observations"],"article_type":"original","date_updated":"2022-08-18T11:04:05Z","volume":498,"issue":"2","date_created":"2022-07-07T10:36:01Z","_id":"11529","external_id":{"arxiv":["2008.01731"]},"citation":{"ieee":"J.

Confirmations of this model exist for present times, but it is less clear in the early Universe. Here, we use the morphology of giant Ly α nebulae around AGNs at redshift z ∼ 3 to probe AGN emission and therefore the validity of the AGN unification model at this redshift. We compare the spatial morphology of 19 nebulae previously found around type I AGNs with a new sample of four Ly α nebulae detected around type II AGNs. Using two independent techniques, we find that nebulae around type II AGNs are more asymmetric than around type I, at least at radial distances r > 30 physical kpc (pkpc) from the ionizing source. We conclude that the type I and type II AGNs in our sample show evidence of different surrounding ionizing geometries. This suggests that the classical AGN unification model is also valid for high-redshift sources. Finally, we discuss how the lack of asymmetry in the inner parts (r ≲ 30 pkpc) and the associated high values of the He II to Ly α ratios in these regions could indicate additional sources of (hard) ionizing radiation originating within or in proximity of the AGN host galaxies. This work demonstrates that the morphologies of giant Ly α nebulae can be used to understand and study the geometry of high-redshift AGNs on circumnuclear scales and it lays the foundation for future studies using much larger statistical samples.","lang":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","article_processing_charge":"No","language":[{"iso":"eng"}],"oa_version":"Preprint","extern":"1","status":"public","oa":1,"publication_status":"published","publication_identifier":{"eissn":["1365-2966"],"issn":["0035-8711"]},"year":"2020","date_published":"2020-06-01T00:00:00Z","quality_controlled":"1","publisher":"Oxford University Press","page":"1874-1887","month":"06","intvolume":" 495","day":"01","arxiv":1,"citation":{"apa":"den Brok, J.

Based on Hubble Space Telescope imaging, we determine that the average UV continuum magnitude is fainter than −16 (≈ 0.01 L⋆), implying a median Lyman-α equivalent width of 259 Å. By combining the H α measurement with the UV magnitude, we determine the ionizing photon production efficiency, ξion, a first for such faint galaxies. The measurement of log10 (ξion [Hz erg−1]) = 26.28 (+0.28−0.40) is in excess of literature measurements of both continuum- and emission line-selected samples, implying a more efficient production of ionizing photons in these lower luminosity, Lyman-α-selected systems.

Lyman α (Ly α) emitters (LAEs) at z ∼ 2–6. We find typical stellar masses of 109.3 ± 0.6 M⊙ and star formation rates (SFR) of SFRSED=4.4+10.5−2.4 M⊙ yr−1 and SFRLyα=5.9+6.3−2.6 M⊙ yr−1, combined with very blue UV slopes of β=−2.1+0.5−0.4, but with significant variations within the population. MUV and β are correlated in a similar way to UV-selected sources, but LAEs are consistently bluer. This suggests that LAEs are the youngest and/or most dust-poor subset of the UV-selected population. We also study the Ly α rest-frame equivalent width (EW0) and find 45 ‘extreme’ LAEs with EW0 > 240 Å (3σ), implying a low number density of (7 ± 1) × 10−7 Mpc−3. Overall, we measure little to no evolution of the Ly α EW0 and scale length parameter (w0), which are consistently high (EW0=140+280−70 Å, w0=129+11−11 Å) from z ∼ 6 to z ∼ 2 and below. However, w0 is anticorrelated with MUV and stellar mass. Our results imply that sources selected as LAEs have a high Ly α escape fraction (fesc,Ly α) irrespective of cosmic time, but fesc,Ly α is still higher for UV-fainter and lower mass LAEs. The least massive LAEs (<109.5 M⊙) are typically located above the star formation ‘main sequence’ (MS), but the offset from the MS decreases towards z ∼ 6 and towards 1010 M⊙. Our results imply a lack of evolution in the properties of LAEs across time and reveals the increasing overlap in properties of LAEs and UV-continuum selected galaxies as typical star-forming galaxies at high redshift effectively become LAEs.","lang":"eng"}],"doi":"10.1093/mnras/staa093","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1910.02959"}],"type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"The evolution of rest-frame UV properties, Ly α EWs, and the SFR–stellar mass relation at z ∼ 2–6 for SC4K LAEs"},{"doi":"10.1093/mnras/stz3554","abstract":[{"text":"The observed properties of the Lyman-α (Ly α) emission line are a powerful probe of neutral gas in and around galaxies. We present spatially resolved Ly α spectroscopy with VLT/MUSE targeting VR7, a UV-luminous galaxy at z = 6.532 with moderate Ly α equivalent width (EW0 ≈ 38 Å). These data are combined with deep resolved [CII]158μm spectroscopy obtained with ALMA and UV imaging from HST and we also detect UV continuum with MUSE. Ly α emission is clearly detected with S/N ≈ 40 and FWHM of 374 km s−1. Ly α and [C II] are similarly extended beyond the UV, with effective radius reff = 2.1 ± 0.2 kpc for a single exponential model or reff,Lyα,halo=3.45+1.08−0.87 kpc when measured jointly with the UV continuum. The Ly α profile is broader and redshifted with respect to the [C II] line (by 213 km s−1), but there are spatial variations that are qualitatively similar in both lines and coincide with resolved UV components. This suggests that the emission originates from two components with plausibly different H I column densities. We place VR7 in the context of other galaxies at similar and lower redshift. The Ly α halo scale length is similar at different redshifts and velocity shifts with respect to the systemic are typically smaller. Overall, we find little indications of a more neutral vicinity at higher redshift. This means that the local (∼10 kpc) neutral gas conditions that determine the observed Ly α properties in VR7 resemble the conditions in post-reionization galaxies.","lang":"eng"}],"publication":"Monthly Notices of the Royal Astronomical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","title":"Resolved Lyman-α properties of a luminous Lyman-break galaxy in a large ionized bubble at z = 6.53 ","main_file_link":[{"url":"https://arxiv.org/abs/1909.06376","open_access":"1"}],"publication_status":"published","year":"2020","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"date_published":"2020-02-01T00:00:00Z","publisher":"Oxford University Press","quality_controlled":"1","page":"1778-1790","article_processing_charge":"No","language":[{"iso":"eng"}],"extern":"1","status":"public","oa_version":"Preprint","oa":1,"citation":{"ieee":"J.

Here, we study the X-ray and radio properties of ∼4000 LAEs at 2.2 < z < 6 from the SC4K survey in the COSMOS field. We detect 254 (6.8per cent±0.4per cent) LAEs individually in the X-rays (S/N > 3) with an average luminosity of 1044.31±0.01ergs−1 and average black hole accretion rate (BHAR) of 0.72±0.01 M⊙ yr−1, consistent with moderate to high accreting active galactic neuclei (AGNs). We detect 120 sources in deep radio data (radio AGN fraction of 3.2per cent±0.3per cent). The global AGN fraction (8.6per cent±0.4per cent) rises with Ly α luminosity and declines with increasing redshift. For X-ray-detected LAEs, Ly α luminosities correlate with the BHARs, suggesting that Ly α luminosity becomes a BHAR indicator. Most LAEs (93.1per cent±0.6per cent) at 2 < z < 6 have no detectable X-ray emission (BHARs < 0.017 M⊙ yr−1). The median star formation rate (SFR) of star-forming LAEs from Ly α and radio luminosities is 7.6+6.6−2.8 M⊙ yr−1. The black hole to galaxy growth ratio (BHAR/SFR) for LAEs is <0.0022, consistent with typical star-forming galaxies and the local BHAR/SFR relation. We conclude that LAEs at 2 < z < 6 include two different populations: an AGN population, where Ly α luminosity traces BHAR, and another with low SFRs which remain undetected in even the deepest X-ray stacks but is detected in the radio stacks."}],"publication":"Monthly Notices of the Royal Astronomical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","title":"The X-ray and radio activity of typical and luminous Ly α emitters from z ∼ 2 to z ∼ 6: Evidence for a diverse, evolving population","main_file_link":[{"url":"https://arxiv.org/abs/1909.11672","open_access":"1"}],"publication_status":"published","year":"2020","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"date_published":"2020-04-01T00:00:00Z","publisher":"Oxford University Press","quality_controlled":"1","page":"3341-3362","article_processing_charge":"No","language":[{"iso":"eng"}],"extern":"1","status":"public","oa_version":"Preprint","oa":1,"citation":{"ieee":"J.

We review recent results from (spectroscopic) follow-up studies of the rest-frame UV, Lyman-α and [CII] emission in luminous galaxies observed ∼500 Myr after the Big Bang with ALMA, HST/WFC3 and VLT/X-SHOOTER. These galaxies likely reside in early ionised bubbles and are complex systems, consisting of multiple well separated and resolved components where traces of metals are already present.","lang":"eng"}]},{"date_updated":"2022-08-22T07:04:45Z","article_type":"original","author":[{"full_name":"Zinn, Joel C.","last_name":"Zinn","first_name":"Joel C."},{"last_name":"Stello","first_name":"Dennis","full_name":"Stello, Dennis"},{"last_name":"Elsworth","first_name":"Yvonne","full_name":"Elsworth, Yvonne"},{"first_name":"Rafael A.","last_name":"García","full_name":"García, Rafael A."},{"full_name":"Kallinger, Thomas","last_name":"Kallinger","first_name":"Thomas"},{"full_name":"Mathur, Savita","last_name":"Mathur","first_name":"Savita"},{"last_name":"Mosser","first_name":"Benoît","full_name":"Mosser, Benoît"},{"first_name":"Lisa Annabelle","last_name":"Bugnet","id":"d9edb345-f866-11ec-9b37-d119b5234501","orcid":"0000-0003-0142-4000","full_name":"Bugnet, Lisa Annabelle"},{"first_name":"Caitlin","last_name":"Jones","full_name":"Jones, Caitlin"},{"last_name":"Hon","first_name":"Marc","full_name":"Hon, Marc"},{"first_name":"Sanjib","last_name":"Sharma","full_name":"Sharma, Sanjib"},{"last_name":"Schönrich","first_name":"Ralph","full_name":"Schönrich, Ralph"},{"full_name":"Warfield, Jack T.","last_name":"Warfield","first_name":"Jack T."},{"full_name":"Luger, Rodrigo","first_name":"Rodrigo","last_name":"Luger"},{"full_name":"Pinsonneault, Marc H.","first_name":"Marc H.","last_name":"Pinsonneault"},{"full_name":"Johnson, Jennifer A.","last_name":"Johnson","first_name":"Jennifer A."},{"first_name":"Daniel","last_name":"Huber","full_name":"Huber, Daniel"},{"last_name":"Aguirre","first_name":"Victor Silva","full_name":"Aguirre, Victor Silva"},{"first_name":"William J.","last_name":"Chaplin","full_name":"Chaplin, William J."},{"last_name":"Davies","first_name":"Guy R.","full_name":"Davies, Guy R."},{"full_name":"Miglio, Andrea","last_name":"Miglio","first_name":"Andrea"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"date_created":"2022-07-18T13:27:26Z","_id":"11610","volume":251,"acknowledgement":"We thank the referee for comments that strengthened the manuscript.

Asteroseismology is the most precise method of providing such information for field star populations en masse, but existing samples for the most part have been limited to a few narrow fields of view by the CoRoT and Kepler missions. In an effort to provide well-characterized stellar parameters across a wide range in Galactic position, we present the second data release of red giant asteroseismic parameters for the K2 Galactic Archaeology Program (GAP). We provide ${\\nu }_{\\max }$ and ${\\rm{\\Delta }}\\nu $ based on six independent pipeline analyses; first-ascent red giant branch (RGB) and red clump (RC) evolutionary state classifications from machine learning; and ready-to-use radius and mass coefficients, κR and κM, which, when appropriately multiplied by a solar-scaled effective temperature factor, yield physical stellar radii and masses. In total, we report 4395 radius and mass coefficients, with typical uncertainties of 3.3% (stat.) ± 1% (syst.) for κR and 7.7% (stat.) ± 2% (syst.) for κM among RGB stars, and 5.0% (stat.) ± 1% (syst.) for κR and 10.5% (stat.) ± 2% (syst.) for κM among RC stars. We verify that the sample is nearly complete—except for a dearth of stars with ${\\nu }_{\\max }\\lesssim 10\\mbox{--}20\\,\\mu \\mathrm{Hz}$—by comparing to Galactic models and visual inspection. Our asteroseismic radii agree with radii derived from Gaia Data Release 2 parallaxes to within 2.2% ± 0.3% for RGB stars and 2.0% ± 0.6% for RC stars."}],"main_file_link":[{"url":"https://arxiv.org/abs/2012.04051","open_access":"1"}],"title":"The K2 galactic archaeology program data release 2: Asteroseismic results from campaigns 4, 6, and 7","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article"},{"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2001.04653"}],"title":"Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1038/s41550-019-0975-9","publication":"Nature Astronomy","abstract":[{"text":"Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies1. Although these accreted stellar populations can be forensically identified as kinematically distinct structures within the Galaxy, it is difficult in general to date precisely the age at which any one merger occurred. Recent results have revealed a population of stars that were accreted via the collision of a dwarf galaxy, called Gaia–Enceladus1, leading to substantial pollution of the chemical and dynamical properties of the Milky Way. Here we identify the very bright, naked-eye star ν Indi as an indicator of the age of the early in situ population of the Galaxy. We combine asteroseismic, spectroscopic, astrometric and kinematic observations to show that this metal-poor, alpha-element-rich star was an indigenous member of the halo, and we measure its age to be 11.0±0.7 (stat) ±0.8 (sys) billion years. The star bears hallmarks consistent with having been kinematically heated by the Gaia–Enceladus collision. Its age implies that the earliest the merger could have begun was 11.6 and 13.2 billion years ago, at 68% and 95% confidence, respectively. Computations based on hierarchical cosmological models slightly reduce the above limits.","lang":"eng"}],"language":[{"iso":"eng"}],"article_processing_charge":"No","oa":1,"oa_version":"Preprint","extern":"1","status":"public","date_published":"2020-04-01T00:00:00Z","publication_status":"published","publication_identifier":{"eissn":["2397-3366"]},"year":"2020","page":"382-389","quality_controlled":"1","publisher":"Springer Nature","month":"04","arxiv":1,"intvolume":" 4","day":"01","scopus_import":"1","citation":{"ama":"Chaplin WJ, Serenelli AM, Miglio A, et al.

The launch of the NASA Transiting Exoplanet Survey Satellite (TESS) mission has enabled seismic-based inferences to go full sky—providing a clear advantage for large ensemble studies of the different Milky Way components. Here we demonstrate its potential for investigating the Galaxy by carrying out the first asteroseismic ensemble study of red giant stars observed by TESS. We use a sample of 25 stars for which we measure their global asteroseimic observables and estimate their fundamental stellar properties, such as radius, mass, and age. Significant improvements are seen in the uncertainties of our estimates when combining seismic observables from TESS with astrometric measurements from the Gaia mission compared to when the seismology and astrometry are applied separately. Specifically, when combined we show that stellar radii can be determined to a precision of a few percent, masses to 5%–10%, and ages to the 20% level. This is comparable to the precision typically obtained using end-of-mission Kepler data.","lang":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1912.07604","open_access":"1"}],"title":"Detection and characterization of oscillating red giants: First results from the TESS satellite","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2020-02-01T00:00:00Z","year":"2020","publication_status":"published","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"quality_controlled":"1","publisher":"IOP Publishing","language":[{"iso":"eng"}],"article_number":"L34","article_processing_charge":"No","oa":1,"oa_version":"Preprint","extern":"1","status":"public"},{"abstract":[{"text":"The recent discovery of low-amplitude dipolar oscillation mixed modes in massive red giants indicates the presence of a missing physical process inside their cores. Stars more massive than ∼ 1.3 M⊙ are known to develop a convective core during the main-sequence: the dynamo process triggered by this convection could be the origin of a strong magnetic field inside the core of the star, trapped when it becomes stably stratified and for the rest of its evolution. The presence of highly magnetized white dwarfs strengthens the hypothesis of buried fossil magnetic fields inside the core of evolved low-mass stars. If such a fossil field exists, it should affect the mixed modes of red giants as they are sensitive to processes affecting the deepest layers of these stars. The impact of a magnetic field on dipolar oscillations modes was one of Pr. Michael J. Thompson’s research topics during the 90s when preparing the helioseismic SoHO space mission. As the detection of gravity modes in the Sun is still controversial, the investigation of the solar oscillation modes did not provide any hint of the existence of a magnetic field in the solar radiative core. Today we have access to the core of evolved stars thanks to the asteroseismic observation of mixed modes from CoRoT, Kepler, K2 and TESS missions. The idea of applying and generalizing the work done for the Sun came from discussions with Pr. Michael Thompson in early 2018 before we lost him. Following the path we drew together, we theoretically investigate the effect of a stable axisymmetric mixed poloidal and toroidal magnetic field, aligned with the rotation axis of the star, on the mixed modes frequencies of a typical evolved low-mass star. This enables us to estimate the magnetic perturbations to the eigenfrequencies of mixed dipolar modes, depending on the magnetic field strength and the evolutionary state of the star. We conclude that strong magnetic fields of ∼ 1MG should perturb the mixed-mode frequency pattern enough for its effects to be detectable inside current asteroseismic data.","lang":"eng"}],"publication":"Dynamics of the Sun and Stars","doi":"10.1007/978-3-030-55336-4_33","title":"The impact of a fossil magnetic field on dipolar mixed-mode frequencies in sub- and red-giant stars","type":"book_chapter","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2012.08684"}],"quality_controlled":"1","publisher":"Springer Nature","series_title":"ASSSP","page":"251-257","publication_status":"published","year":"2020","publication_identifier":{"isbn":["978-3-030-55335-7"],"eissn":["1570-6605"],"eisbn":["978-3-030-55336-4"],"issn":["1570-6591"]},"date_published":"2020-12-19T00:00:00Z","oa_version":"Preprint","extern":"1","status":"public","oa":1,"edition":"1","article_processing_charge":"No","language":[{"iso":"eng"}],"alternative_title":["Astrophysics and Space Science Proceedings"],"external_id":{"arxiv":["2012.08684"]},"editor":[{"first_name":"Mario","last_name":"Monteiro","full_name":"Monteiro, Mario"},{"full_name":"Garcia, Rafael A","first_name":"Rafael A","last_name":"Garcia"},{"last_name":"Christensen-Dalsgaard","first_name":"Jorgen","full_name":"Christensen-Dalsgaard, Jorgen"},{"last_name":"McIntosh","first_name":"Scott W","full_name":"McIntosh, Scott W"}],"citation":{"chicago":"Bugnet, Lisa Annabelle, V.

Starting with the seminal work of Onak and Rubinfeld (in: Proceedings of the ACM symposium on theory of computing (STOC), 2010), this problem has received significant attention in recent years. Very recently, extending the framework of Baswana et al. (in: Proceedings of the IEEE symposium on foundations of computer science (FOCS), 2011) , Solomon (in: Proceedings of the IEEE symposium on foundations of computer science (FOCS), 2016) gave a randomized dynamic algorithm for this problem that has an approximation ratio of 2 and an amortized update time of O(1) with high probability. This algorithm requires the assumption of an oblivious adversary, meaning that the future sequence of edge insertions/deletions in the graph cannot depend in any way on the algorithm’s past output. A natural way to remove the assumption on oblivious adversary is to give a deterministic dynamic algorithm for the same problem in O(1) update time. In this paper, we resolve this question. We present a new deterministic fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover and maximum fractional matching, with an amortized update time of O(1). Previously, the best deterministic algorithm for this problem was due to Bhattacharya et al. (in: Proceedings of the ACM-SIAM symposium on discrete algorithms (SODA), 2015); it had an approximation ratio of (2+ε) and an amortized update time of O(logn/ε2). Our result can be generalized to give a fully dynamic O(f3)-approximate algorithm with O(f2) amortized update time for the hypergraph vertex cover and fractional hypergraph matching problem, where every hyperedge has at most f vertices."}],"publication":"Algorithmica","doi":"10.1007/s00453-019-00630-4","status":"public","extern":"1","oa_version":"Published Version","oa":1,"article_processing_charge":"No","language":[{"iso":"eng"}],"publisher":"Springer Nature","quality_controlled":"1","page":"1057-1080","publication_identifier":{"issn":["0178-4617"],"eissn":["1432-0541"]},"year":"2020","publication_status":"published","date_published":"2020-04-01T00:00:00Z"},{"abstract":[{"text":"Recent advances in synthetic posttranslational protein circuits are substantially impacting the landscape of cellular engineering and offer several advantages compared to traditional gene circuits. However, engineering dynamic phenomena such as oscillations in protein-level circuits remains an outstanding challenge. Few examples of biological posttranslational oscillators are known, necessitating theoretical progress to determine realizable oscillators. We construct mathematical models for two posttranslational oscillators, using few components that interact only through reversible binding and phosphorylation/dephosphorylation reactions. Our designed oscillators rely on the self-assembly of two protein species into multimeric functional enzymes that respectively inhibit and enhance this self-assembly. We limit our analysis to within experimental constraints, finding (i) significant portions of the restricted parameter space yielding oscillations and (ii) that oscillation periods can be tuned by several orders of magnitude using recent advances in computational protein design. Our work paves the way for the rational design and realization of protein-based dynamic systems.","lang":"eng"}],"publication":"Science Advances","doi":"10.1126/sciadv.abc1939","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Self-assembly-based posttranslational protein oscillators","file":[{"file_size":1259758,"file_name":"2020_ScienceAdv_Kimchi.pdf","success":1,"date_updated":"2021-04-12T08:33:23Z","file_id":"9320","checksum":"eb6d950b6a68ddc4a2fb31ec80a2a1bd","access_level":"open_access","creator":"dernst","content_type":"application/pdf","relation":"main_file","date_created":"2021-04-12T08:33:23Z"}],"ddc":["570"],"quality_controlled":"1","publication_status":"published","year":"2020","date_published":"2020-12-16T00:00:00Z","status":"public","extern":"1","oa_version":"Published Version","oa":1,"has_accepted_license":"1","article_processing_charge":"No","article_number":"eabc1939","language":[{"iso":"eng"}],"citation":{"ieee":"O.

LS is a poorly understood pediatric disorder featuring brain-specific anomalies and early death. To study the LS pathomechanism, we here compared OXPHOS proteomes between various Ndufs4−/− mouse tissues. Ndufs4−/− animals displayed significantly lower CI subunit levels in brain/diaphragm relative to other tissues (liver/heart/kidney/skeletal muscle), whereas other OXPHOS subunit levels were not reduced. Absence of NDUFS4 induced near complete absence of the NDUFA12 accessory subunit, a 50% reduction in other CI subunit levels, and an increase in specific CI assembly factors. Among the latter, NDUFAF2 was most highly increased. Regarding NDUFS4, NDUFA12 and NDUFAF2, identical results were obtained in Ndufs4−/− mouse embryonic fibroblasts (MEFs) and NDUFS4-mutated LS patient cells. Ndufs4−/− MEFs contained active CI in situ but blue-native-PAGE highlighted that NDUFAF2 attached to an inactive CI subcomplex (CI-830) and inactive assemblies of higher MW. In NDUFA12-mutated LS patient cells, NDUFA12 absence did not reduce NDUFS4 levels but triggered NDUFAF2 association to active CI. BN-PAGE revealed no such association in LS patient fibroblasts with mutations in other CI subunit-encoding genes where NDUFAF2 was attached to CI-830 (NDUFS1, NDUFV1 mutation) or not detected (NDUFS7 mutation). Supported by enzymological and CI in silico structural analysis, we conclude that absence of NDUFS4 induces near complete absence of NDUFA12 but not vice versa, and that NDUFAF2 stabilizes active CI in Ndufs4−/− mice and LS patient cells, perhaps in concert with mitochondrial inner membrane lipids."}],"language":[{"iso":"eng"}],"article_number":"148213","article_processing_charge":"No","has_accepted_license":"1","oa":1,"oa_version":"Published Version","status":"public","date_published":"2020-08-01T00:00:00Z","publication_status":"published","year":"2020","publication_identifier":{"issn":["00052728"],"eissn":["18792650"]},"quality_controlled":"1","publisher":"Elsevier"},{"citation":{"ama":"Dekoninck S, Hannezo EB, Sifrim A, et al.

However, little is known about the cellular dynamics that mediate postnatal growth. By combining in vivo clonal lineage tracing, proliferation kinetics, single-cell transcriptomics, andin vitro micro-pattern experiments, we resolved the cellular dynamics taking place during postnatal skin epidermis expansion. Our data revealed that harmonious growth is engineered by a single population of developmental progenitors presenting a fixed fate imbalance of self-renewing divisions with an ever-decreasing proliferation rate. Single-cell RNA sequencing revealed that epidermal developmental progenitors form a more uniform population compared with adult stem and progenitor cells. Finally, we found that the spatial pattern of cell division orientation is dictated locally by the underlying collagen fiber orientation. Our results uncover a simple design principle of organ growth where progenitors and differentiated cells expand in harmony with their surrounding tissues.","lang":"eng"}],"publication":"Cell","file":[{"file_id":"7795","date_updated":"2020-07-14T12:48:03Z","file_name":"2020_Cell_Dekoninck.pdf","file_size":17992888,"date_created":"2020-05-04T10:20:55Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","creator":"dernst","checksum":"e2114902f4e9d75a752e9efb5ae06011"}],"ddc":["570"],"title":"Defining the design principles of skin epidermis postnatal growth","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","type":"journal_article","publication_status":"published","year":"2020","publication_identifier":{"eissn":["10974172"],"issn":["00928674"]},"date_published":"2020-04-30T00:00:00Z","quality_controlled":"1","publisher":"Elsevier","page":"604-620.e22","article_processing_charge":"No","language":[{"iso":"eng"}],"oa_version":"Published Version","status":"public","has_accepted_license":"1","oa":1}]
