These galaxies have been selected on their Ly α (73), [O II] (285), H β/[O III] (387) or H α (362) emission line, and have been classified with optical to near-infrared colours. A subsample of 98 sources have reliable redshifts from multiple narrow-band (e.g. [O II]–H α) detections and/or spectroscopy. In this survey paper, we present the observations, selection and catalogues of emitters. We measure number densities of Ly α, [O II], H β/[O III] and H α and confirm strong luminosity evolution in star-forming galaxies from z ∼ 0.4 to ∼5, in agreement with previous results. To demonstrate the usefulness of dual-line emitters, we use the sample of dual [O II]–H α emitters to measure the observed [O II]/H α ratio at z = 1.47. The observed [O II]/H α ratio increases significantly from 0.40 ± 0.01 at z = 0.1 to 0.52 ± 0.05 at z = 1.47, which we attribute to either decreasing dust attenuation with redshift, or due to a bias in the (typically) fibre measurements in the local Universe that only measure the central kpc regions. At the bright end, we find that both the H α and Ly α number densities at z ≈ 2.2 deviate significantly from a Schechter form, following a power law. We show that this is driven entirely by an increasing X-ray/active galactic nucleus fraction with line luminosity, which reaches ≈100 per cent at line luminosities L ≳ 3 × 1044 erg s−1.","lang":"eng"}],"oa":1,"date_created":"2022-07-12T11:01:35Z","publication_identifier":{"issn":["0035-8711","1365-2966"]},"intvolume":"       471","publisher":"Oxford University Press","author":[{"last_name":"Matthee","full_name":"Matthee, Jorryt J","orcid":"0000-0003-2871-127X","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J"},{"last_name":"Sobral","full_name":"Sobral, David","first_name":"David"},{"last_name":"Best","full_name":"Best, Philip","first_name":"Philip"},{"first_name":"Ian","last_name":"Smail","full_name":"Smail, Ian"},{"last_name":"Bian","full_name":"Bian, Fuyan","first_name":"Fuyan"},{"full_name":"Darvish, Behnam","last_name":"Darvish","first_name":"Behnam"},{"first_name":"Huub","last_name":"Röttgering","full_name":"Röttgering, Huub"},{"full_name":"Fan, Xiaohui","last_name":"Fan","first_name":"Xiaohui"}]}
