VizieR Online Data Catalog: ALMA/NOEMA high-z star-forming galaxies (Birkin+, 2021)

Our 61 targets are selected from ALMA-identified 870-μm-selected SMGs in the AS2COSMOS (Simpson et al. 2020MNRAS.495.3409S, Cat. J/MNRAS/495/3409), AS2UDS (Stach et al. 2019MNRAS.487.4648S), and ALESS (Hodge et al. 2013ApJ...768...91H, Cat. J/ApJ/768/91) surveys.

A total of 31 sources that lack existing spectroscopic redshifts, which were targeted with scans in the 3-mm band. These sources comprise two subsets, first SMGs with the brightest 870-μm fluxes in the AS2COSMOS and AS2UDS surveys, and a second subset of sources from ALESS that span a wider range in submillimetre flux, but are chosen to be faint in the optical/near-infrared

A total of 30 sources with existing rest-frame optical/UV spectroscopic redshifts. Four of these sources are taken from AS2UDS (Dudzeviciute et al. 2020MNRAS.494.3828D, Cat. J/MNRAS/494/3828), and the remaining 26 are taken from ALESS (Danielson et al. 2017ApJ...840...78D, Cat. J/ApJ/840/78). These sources are typically brighter in the optical and near-infrared, and fainter in the submillimetre than the scan sample.

Observations were obtained from six projects, four with ALMA and two with NOEMA/PolyFix, between 2017 and 2020. Fifteen targets from the scan sample, five from AS2COSMOS, and ten from AS2UDS, were observed with NOEMA/PolyFix in projects S18CG and W18EL. The remaining 46 targets were observed with ALMA in projects 2016.1.00564.S, 2017.1.01163.S, 2017.1.01512.S, and 2019.1.00337.S. Sixteen of the targets in the scan sample (three from AS2UDS, thirteen from ALESS) were observed using five tunings to achieve 32GHz of bandwidth covering ~82-114GHz. All 30 targets in the spec-z sample were observed using single tunings centred on the frequency of the CO line expected in the 3-mm band (ALMA band 3).
