cds-question@unistra.fractive-galactic-nucleiradio-continuum-emissionmillimeter-astronomysubmillimeter-astronomysurveysastronomical-object-identificationWe report on extragalactic sources detected in a 455deg^2^ map of the southern sky made with data at a frequency of 148GHz from the Atacama Cosmology Telescope (ACT) 2008 observing season. We provide a catalog of 157 sources with flux densities spanning two orders of magnitude: from 15mJy to 1500mJy. Comparison to other catalogs shows that 98% of the ACT detections correspond to sources detected at lower radio frequencies. Three of the sources appear to be associated with the brightest cluster galaxies of low-redshift X-ray-selected galaxy clusters. Estimates of the radio to millimeter-wave spectral indices and differential counts of the sources further bolster the hypothesis that they are nearly all radio sources, and that their emission is not dominated by re-emission from warm dust. In a bright (>50mJy) 148GHz selected sample with complete cross-identifications from the Australia Telescope 20GHz survey, we observe an average steepening of the spectra between 5, 20, and 148GHz with median spectral indices of {alpha}_5-20_=-0.07+/-0.06, {alpha}_20-148_=-0.39+/-0.04, and {alpha}_5-148_=-0.20+/-0.03. When the measured spectral indices are taken into account, the 148GHz differential source counts are consistent with previous measurements at 30GHz in the context of a source count model dominated by radio sources. Extrapolating with an appropriately rescaled model for the radio source counts, the Poisson contribution to the spatial power spectrum from synchrotron-dominated sources with flux density less than 20mJy is C^Sync^=(2.8+/-0.3)x10^-6^{mu}K^2^.2011ApJ...731..100Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/731/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/402/2403 : Australia Telescope 20GHz Survey Catalog (AT20G)J/ApJ/718/587 : The Fermi-AT20G catalog (Mahony+, 2010)J/ApJ/719/763 : Millimeter-wave sources in the SPT survey (Vieira+, 2010)J/MNRAS/384/775 : Bright Source Sample of AT20G Survey (Massardi+, 2008)http://www.princeton.edu/act/ : ACT web sitehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/731/100https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/731/100http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/731/100https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/731/100https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/731/100http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/731/100GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/731/100/tablea1 (ACT (Atacama Cosmology Telescope) high significance 148GHz extragalactic source catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/731/100/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/731/100/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/731/100/tablea1?GETtext/xml+votable180.050000true4.70833-51.248330.0055555555555555565/8470 6/33279 33621 33622 33623 33626 33629 33631 33634 33639 33640 33645 33648 33649 33650 33652 33654 33659 33660 33679 33681 33684 33689 33690 33692 33700 33702 33703 33704 33707 33711 33712 33714 33717 33719 33720 33722 33724 33728 33729 33730 33736 33740 33744 33760 33870 33871 33875 33884 33891 33893 33906 33907 33913 33940 33943 33945 33949 33950 33954 33957 33958 33964 33967 33968 33973 33975 33984 33985 33986 33992 33994 33996 33997 34000 34048 34050 34051 34056 34064 34065 34313 34317 34320 34895 34901 34903 34904 34911 34918 34919 34926 34927 34929 34930 34931 34932 34936 34937 34938 34964 34966 34967 34973 34981 34993 34995 35000 35001 35013 35016 35017 35074 35076 35077 35079 35082 35083 35334 35342 39062 39065 39077 39078 39079 39081 39082 39084 39086 39087 39088 39091 394259.806582964055855e-23 9.806582964055855e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/731/100?format=asciiRadiodefaultJ/ApJ/731/100/tablea1ACT (Atacama Cosmology Telescope) high significance 148GHz extragalactic source catalogrecnoRecord number assigned by the VizieR team.
