cds-question@unistra.frgalaxiesinfrared-sourcesinfrared-photometrymillimeter-astronomysubmillimeter-astronomyredshiftedWe use Spitzer-IRAC data to identify near-infrared counterparts to submillimeter galaxies detected with Herschel-SPIRE at 250{mu}m in the Herschel Astrophysical Terahertz Large Area Survey. Using a likelihood ratio analysis we identify 146 reliable IRAC counterparts to 123 SPIRE sources out of the 159 in the survey area. We find that, compared to the field population, the SPIRE counterparts occupy a distinct region of the 3.6 and 4.5{mu}m color-magnitude space, and we use this property to identify 23 further counterparts to 13 SPIRE sources. The IRAC identification rate of 86% is significantly higher than those that have been demonstrated with wide-field ground-based optical and near-IR imaging of Herschel fields. We estimate a false identification rate of 3.6%, corresponding to 4-5 sources. Among the 73 counterparts that are undetected in Sloan Digital Sky Survey, 57 have both 3.6 and 4.5{mu}m coverage. Of these, 43 have [3.6]-[4.5]>0, indicating that they are likely to be at z>~1.4. Thus, ~40% of identified SPIRE galaxies are likely to be high-redshift (z>~1.4) sources. We discuss the statistical properties of the IRAC-identified SPIRE galaxy sample including far-IR luminosities, dust temperatures, star formation rates, and stellar masses. The majority of our detected galaxies have 10^10^-10^11^L_{sun}_ total IR luminosities and are not intense starbursting galaxies as those found at z~2, but they have a factor of 2-3 above average specific star formation rates compared to near-IR selected galaxy samples.2012ApJ...756...28Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/756/28CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/329 : VIKING catalogue data release 1 (Edge+, 2013)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)VII/252 : SDSS-DR5 quasar catalog (Schneider+, 2007)J/ApJ/749/65 : Strongly lensed galaxies in H-ATLAS (Gonzalez-Nuevo+, 2012)J/MNRAS/421/3027 : Statisical study of galaxy dust emissions (Bourne+, 2012)J/AJ/143/125 : SED of 113 dust-obscured galaxies at z~2 (Melbourne+, 2012)J/MNRAS/415/2336 : Herschel-ATLAS Science Demonstration Catalog (Rigby+, 2011)J/MNRAS/413/2314 : Radio and MIR counterpart of submm galaxies (Biggs+, 2011)J/MNRAS/413/971 : Galaxy And Mass Assembly (GAMA) DR1 (Driver+, 2011)J/ApJ/699/1610 : Spitzer survey of submillimeter galaxies (Hainline+, 2009)http://www.h-atlas.org/ : H-ATLAS web sitehttp://www.sdss.org/ : SDSS home pagehttp://www.eso.org/sci/observing/phase3/data_releases.html : ESO VISTAhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/756/28https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/756/28http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/756/28https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/756/28https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/756/28http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/756/28GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/756/28/table2 (Combined photometry for IRAC identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/756/28/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/756/28/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/756/28/table2?GETtext/xml+votable180.050000true135.79820830.65177780.0055555555555555566/4097 27298 27299 27305 27307 27308 27310 409573.2031150387835462e-22 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/756/28?format=asciiOpticalInfraredRadiodefaultJ/ApJ/756/28/table2Combined photometry for IRAC identificationse_z[0/0.3]? z uncertaintystat.error;src.redshiftfloatnullablerecnoRecord number assigned by the VizieR team.
