  text: We present the results from a MUSE survey of twelve z ≃ 3.15 quasars, which
    were selected to be much fainter (20 < iSDSS < 23) than in previous studies of
    giant Ly α nebulae around the brightest quasars (16.6 < iAB < 18.7). We detect
    H I Ly α nebulae around 100 per cent of our target quasars, with emission extending
    to scales of at least 60 physical kpc, and up to 190 pkpc. We explore correlations
    between properties of the nebulae and their host quasars, with the goal of connecting
    variations in the properties of the illuminating QSO to the response in nebular
    emission. We show that the surface brightness profiles of the nebulae are similar
    to those of nebulae around bright quasars, but with a lower normalization. Our
    targeted quasars are on average 3.7 mag (≃30 times) fainter in UV continuum than
    our bright reference sample, and yet the nebulae around them are only 4.3 times
    fainter in mean Ly α surface brightness, measured between 20 and 50 pkpc. We find
    significant correlations between the surface brightness of the nebula and the
    luminosity of the quasar in both UV continuum and Ly α. The latter can be interpreted
    as evidence for a substantial contribution from unresolved inner parts of the
    nebulae to the narrow components seen in the Ly α lines of some of our faint quasars,
    possibly from the inner circumgalactic medium or from the host galaxy’s interstellar
    medium.

  at the European Organisation for Astronomical Research in the Southern Hemisphere
  under the MUSE GTO programme. The major analysis and production of figures in this
  work was conducted in Python, using standard libraries which include NumPy (Harris
  et al. 2020), SciPy (Virtanen et al. 2020), Matplotlib (Hunter 2007) and the interactive
  command shell IPython (Pérez & Granger 2007). This research also made use of Astropy,
  a community-developed core Python package for Astronomy (Astropy Collaboration et
  al. 2013), and Photutils, an Astropy package for detection and photometry of astronomica
  sources (Bradley et al. 2019). The python interface dustmaps (Green 2018) was used
  to query galactic extinction maps. topcat, a graphical tool for manipulating tabular
  data, was also utilized in this analysis (Taylor 2005). This research has made use
  of the "Aladin sky atlas" developed at CDS, Strasbourg Observatory, France (Bonnarel
  et al. 2000).

  text: A prediction of the classic active galactic nucleus (AGN) unification model
    is the presence of ionization cones with different orientations depending on the
    AGN type. 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.

  text: While traditionally associated with active galactic nuclei (AGN), the properties
    of the C II] (λ = 2326 Å), C III] (λ, λ = 1907, 1909 Å) and C IV (λ, λ = 1549,
    1551 Å) emission lines are still uncertain as large, unbiased samples of sources
    are scarce. We present the first blind, statistical study of C II], C III] and
    C IV emitters at z ∼ 0.68, 1.05, 1.53, respectively, uniformly selected down to
    a flux limit of ∼4 × 10−17 erg s−1 cm−1 through a narrow-band survey covering
    an area of ∼1.4 deg2 over COSMOS and UDS. We detect 16 C II], 35 C III] and 17
    C IV emitters, whose nature we investigate using optical colours as well as Hubble
    Space Telescope (HST), X-ray, radio and far-infrared data. We find that z ∼ 0.7
    C II] emitters are consistent with a mixture of blue (UV slope β = −2.0 ± 0.4)
    star-forming (SF) galaxies with discy HST structure and AGN with Seyfert-like
    morphologies. Bright C II] emitters have individual X-ray detections as well as
    high average black hole accretion rates (BHARs) of ∼0.1 M⊙ yr−1. C III] emitters
    at z ∼ 1.05 trace a general population of SF galaxies, with β = −0.8 ± 1.1, a
    variety of optical morphologies, including isolated and interacting galaxies and
    low BHAR (<0.02 M⊙ yr−1). Our C IV emitters at z ∼ 1.5 are consistent with young,
    blue quasars (β ∼ −1.9) with point-like optical morphologies, bright X-ray counterparts
    and large BHAR (0.8  M⊙ yr−1). We also find some surprising C II], C III] and
    C IV emitters with rest-frame equivalent widths (EWs) that could be as large as
    50–100 Å. AGN or spatial offsets between the UV continuum stellar disc and the
    line-emitting regions may explain the large EW. These bright C II], C III] and
    C IV emitters are ideal candidates for spectroscopic follow-up to fully unveil
    their nature.

  text: Recently, the C III] and C IV emission lines have been observed in galaxies
    in the early Universe (z > 5), providing new ways to measure their redshift and
    study their stellar populations and active galactic nuclei (AGN). We explore the
    first blind C II], C III] and C IV survey (z ∼ 0.68, 1.05, 1.53, respectively)
    presented in Stroe et al. (2017). We derive luminosity functions (LF) and study
    properties of C II], C III] and C IV line emitters through comparisons to the
    LFs of H α and Ly α emitters, UV selected star-forming (SF) galaxies and quasars
    at similar redshifts. The C II] LF at z ∼ 0.68 is equally well described by a
    Schechter or a power-law LF, characteristic of a mixture of SF and AGN activity.
    The C III] LF (z ∼ 1.05) is consistent to a scaled down version of the Schechter
    H α and Ly α LF at their redshift, indicating a SF origin. In stark contrast,
    the C IV LF at z ∼ 1.53 is well fit by a power-law, quasar-like LF. We find that
    the brightest UV sources (MUV < −22) will universally have C III] and C IV emission.
    However, on average, C III] and C IV are not as abundant as H α or Ly α emitters
    at the same redshift, with cosmic average ratios of ∼0.02–0.06 to H α and ∼0.01–0.1
    to intrinsic Ly α. We predict that the C III] and C IV lines can only be truly
    competitive in confirming high-redshift candidates when the hosts are intrinsically
    bright and the effective Ly α escape fraction is below 1 per cent. While C III]
    and C IV were proposed as good tracers of young, relatively low-metallicity galaxies
    typical of the early Universe, we find that, at least at z ∼ 1.5, C IV is exclusively
    hosted by AGN/quasars, especially at large line equivalent widths.
