cds-question@unistra.frgalaxiesphotometryinfrared-photometrymillimeter-astronomysubmillimeter-astronomyvisible-astronomysloan-photometryMotivated by the current controversy over the redshift distribution and physical properties of luminous (sub-)mm sources, we have undertaken a new study of the brightest sample of unlensed (sub-)mm sources with pre-Atacama Large Millimeter/submillimeter Array (ALMA) interferometric follow-up in the Cosmological Evolution Survey field. Exploiting the very latest multifrequency supporting data, we find that this sample displays a redshift distribution indistinguishable from that of the lensed sources uncovered with the South Pole Telescope, with z_median_=~3.5. We also find that, over the redshift range z=~2-6, the median stellar mass of the most luminous (sub-) mm sources is M_*_=~ 3x10^11^M_{sun}_, yielding a typical specific star formation rate sSFR=~3Gyr^-1^. Consistent with recent ALMA and the Submillimeter Array studies, we confirm that source blending is not a serious issue in the study of luminous (sub-)mm sources uncovered by ground-based, single-dish surveys; only =~10^-15^% of bright (S_850_=~5-10mJy) (sub-) mm sources arise from significant (i.e. >20%) blends, and so our conclusions are largely unaffected by whether we adopt the original single-dish mm/sub-mm flux densities/positions or the interferometric data. Our results suggest that apparent disagreements over the redshift distribution of (sub-)mm sources are a result of 'down-sizing' in dust-enshrouded star formation, consistent with existing knowledge of the star formation histories of massive galaxies. They also indicate that extreme star-forming galaxies at high redshift are, on average, subject to the same star formation rate-limiting processes as less luminous objects, and lie on the 'main sequence' of star-forming galaxies at z>3.2014MNRAS.444..117Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/444/117CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/385/2225 : AzTEC millimetre survey of COSMOS field (Scott+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/444/117https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/444/117http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/444/117https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/444/117https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/444/117http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/444/117GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/444/117/table1 (The results of our attempt to establish galaxy identifications for the (sub-)mm sources based on statistical associations between the original single-dish (sub-)mm positions and potential counterparts in the multi-wavelength imaging)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/117/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/117/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/117/table1?GETtext/xml+votable180.050000true149.928592.493930.005555555555555556Cone search capability for table J/MNRAS/444/117/table2 (Optical CFHTLS, near-infrared UltraVISTA and IRAC AB magnitudes with errors calculated using 2" diameter aperture measurements corrected to 'total' using the relevant on-image PSF.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/117/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/117/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/117/table2?GETtext/xml+votable180.050000true149.928592.493940.005555555555555556Cone search capability for table J/MNRAS/444/117/table3 (Optical Subaru, near-infrared UltraVISTA and IRAC AB magnitudes with errors calculated using 2" diameter aperture measurements corrected to 'total' using the relevant on-image PSF)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/444/117/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/444/117/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/444/117/table3?GETtext/xml+votable180.050000true150.075292.808420.0055555555555555566/27256 27258-272599.276497240453405e-25 5.21690004175582e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/444/117?format=asciiOpticalInfraredRadiodefaultJ/MNRAS/444/117/table1The results of our attempt to establish galaxy identifications for the (sub-)mm sources based on statistical associations between the original single-dish (sub-)mm positions and potential counterparts in the multi-wavelength imagingSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
