cds-question@unistra.frgalaxiesmillimeter-astronomysubmillimeter-astronomyapparent-magnitudeWe present the catalogue and basic properties of sources in AS2UDS, an 870-{mu}m continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716 single-dish sub-millimetre sources detected in the UKIDSS/UDS field by the SCUBA-2 Cosmology Legacy Survey. In our sensitive ALMA follow-up observations, we detect 708 sub-millimetre galaxies (SMGs) at >4.3{sigma} significance across the ~1{deg}-diameter field. We combine our precise ALMA positions with the extensive multiwavelength coverage in the UDS field which yields spectral energy distributions for our SMGs and a median redshift of z_phot_=2.61+/-0.09. This large sample reveals a statistically significant trend of increasing sub-millimetre flux with redshift suggestive of galaxy downsizing. 101 ALMA maps do not show a>4.3{sigma} SMG, but we demonstrate from stacking Herschel SPIRE observations at these positions, that the vast majority of these blank maps correspond to real single-dish sub-millimetre sources. We further show that these blank maps contain an excess of galaxies at z_phot_=1.5-4 compared to random fields, similar to the redshift range of the ALMA-detected SMGs. In addition, we combine X-ray and mid-infrared active galaxy nuclei activity (AGN) indicators to yield a likely range for the AGN fraction of 8-28 per cent in our sample. Finally, we compare the redshifts of this population of high-redshift, strongly star-forming galaxies with the inferred formation redshifts of massive, passive galaxies being found out to z~2, finding reasonable agreement - in support of an evolutionary connection between these two classes of massive galaxy.2019MNRAS.487.4648Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/487/4648CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/487/4648https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/487/4648http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/487/4648https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/487/4648https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/487/4648http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/487/4648GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/487/4648/table1 (The AS2UDS Catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/487/4648/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/487/4648/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/487/4648/table1?GETtext/xml+votable180.050000true34.62778-5.525450.0055555555555555566/17677 17679 17688 176909.276497240453405e-25 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/487/4648?format=asciiMillimeterdefaultJ/MNRAS/487/4648/table1The AS2UDS CataloguerecnoRecord number assigned by the VizieR team.
