cds-question@unistra.frsurveysradio-sourcesgalaxiescatalogsWe present a catalogue of 191 extragalactic sources detected by the Atacama Cosmology Telescope (ACT) at 148 and/or 218GHz in the 2008 Southern survey. Flux densities span 14 -1700mJy, and we use source spectral indices derived using ACT-only data to divide our sources into two subpopulations: 167 radio galaxies powered by central active galactic nuclei (AGN) and 24 dusty star-forming galaxies (DSFGs). We cross-identify 97 percent of our sources (166 of the AGN and 19 of the DSFGs) with those in currently available catalogues. When combined with flux densities from the Australia Telescope 20GHz survey and follow-up observations with the Australia Telescope Compact Array, the synchrotron-dominated population is seen to exhibit a steepening of the slope of the spectral energy distribution from 20 to 148GHz, with the trend continuing to 218GHz. The ACT dust-dominated source population has a median spectral index, {alpha}_148-218_, of 3.7^+0.62^_-0.86_, and includes both local galaxies and sources with redshift around 6. Dusty sources with no counterpart in existing catalogues likely belong to a recently discovered subpopulation of DSFGs lensed by foreground galaxies or galaxy groups.2014MNRAS.439.1556Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/439/1556CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/731/100 : 148GHz ACT extragalactic sources catalog (Marriage+, 2011)J/MNRAS/402/2403 : Australia Tel. 20GHz Survey Catalog, AT20G (Murphy+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/439/1556https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/439/1556http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/439/1556https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/439/1556https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/439/1556http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/439/1556GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/439/1556/table4 (ACT high significance 148 and 218GHz Extragalactic Source Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/439/1556/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/439/1556/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/439/1556/table4?GETtext/xml+votable180.050000true4.707083-51.2516940.0055555555555555565/8470 6/33279 33621-33622 33626 33629 33631 33634 33639-33640 33645-33646 33648-33650 33652 33654 33659-33660 33679 33681 33683-33684 33689-33690 33692 33700 33703-33704 33707 33711-33714 33717 33719-33720 33722 33724 33728-33730 33736 33739-33740 33744 33760 33762 33870-33871 33875 33879 33884 33886 33891 33893 33900 33903 33906-33907 33913 33917 33940 33943 33945 33949-33950 33954 33957-33958 33962 33964 33967-33968 33973 33975 33984-33986 33992-33994 33996-33997 34000 34050-34051 34055-34056 34058-34059 34064-34065 34082 34306 34312-34313 34317 34320 34878 34895 34901 34903-34904 34910-34911 34918-34919 34926 34929-34932 34936 34938 34964 34966-34967 34973 34981 34991 34993 34999-35000 35004 35013 35016-35017 35074 35076-35077 35079 35082-35083 35092 35334 35342 35346 39016 39057 39060 39062 39065 39077-39079 39081-39082 39086-39088 39091 39095 39099 39115 39138 39425 394571.325213914061602e-23 1.4444831663271462e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/439/1556?format=asciiRadiodefaultJ/MNRAS/439/1556/table4ACT high significance 148 and 218GHz Extragalactic Source CatalogE_S148Error on S148 (upper value)mJystat.error;stat.maxfloatrecnoRecord number assigned by the VizieR team.
