cds-question@unistra.frradio-galaxiesinterstellar-mediumredshiftedstellar-massesThe use of submillimeter dust continuum emission to probe the mass of interstellar dust and gas in galaxies is empirically calibrated using samples of local star-forming galaxies, Planck observations of the Milky Way, and high-redshift submillimeter galaxies. All of these objects suggest a similar calibration, strongly supporting the view that the Rayleigh-Jeans tail of the dust emission can be used as an accurate and very fast probe of the interstellar medium (ISM) in galaxies. We present ALMA Cycle 0 observations of the Band 7 (350GHz) dust emission in 107 galaxies from z=0.2 to 2.5. Three samples of galaxies with a total of 101 galaxies were stellar-mass-selected from COSMOS to have M_*_=~10^11^M_{sun}_:37 at z~0.4, 33 at z~0.9, and 31 at z=2. A fourth sample with six infrared-luminous galaxies at z=2 was observed for comparison with the purely mass-selected samples. From the fluxes detected in the stacked images for each sample, we find that the ISM content has decreased by a factor ~6 from 1 to 2x10^10^M_{sun}_ at both z=2 and 0.9 down to ~2x10^9^M_{sun}_at z=0.4. The infrared-luminous sample at z=2 shows a further ~4 times increase in M_ISM_compared with the equivalent non-infrared-bright sample at the same redshift. The gas mass fractions are ~2%+/-0.5%, 12%+/-3%, 14%+/-2%, and 53%+/-3% for the four subsamples (z=0.4, 0.9, and 2 and infrared-bright galaxies).2014ApJ...783...84Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/783/84CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/284 : COSMOS Multi-Wavelength Photometry Catalog (Capak+, 2007)J/ApJ/827/142 : ALMA observations of GKM stars in Upper Sco (Barenfeld+, 2016)J/ApJ/812/43 : ALMA 870um obs. of HerMES galaxies (Bussmann+, 2015)J/A+A/556/A55 : Photometry of star-forming galaxies (Ilbert+, 2013)J/ApJ/768/91 : ALMA observations of LESS submm galaxies (Hodge+, 2013)J/ApJ/768/74 : CO observations of star-forming galaxies (Tacconi+, 2013)J/A+A/544/A156 : UltraVISTA Catalogue Release DR1 (McCracken+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/783/84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/783/84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/783/84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/783/84https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/783/84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/783/84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/783/84/galaxies (Galaxy sample in band 7 (350GHz): low-z (table5), mid-z (table6), and high-z (table7))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/783/84/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/783/84/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/783/84/galaxies?GETtext/xml+votable180.050000true150.21421.75780.0055555555555555565/6814 6/27245 27247 273442.3390025583187276e-22 2.3390025583187276e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/783/84?format=asciiOpticalRadiodefaultJ/ApJ/783/84/galaxiesGalaxy sample in band 7 (350GHz): low-z (table5), mid-z (table6), and high-z (table7)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
