cds-question@unistra.frgalaxiesinfrared-sourcesinfrared-photometryvisible-astronomybroad-band-photometryWe explore the nature of Infrared Excess sources (IRX), which are proposed as candidates for luminous [LX(2-10keV)>10^43^erg/s] Compton thick (NH>2x10^24^cm^-2^) QSOs at z~~2. Lower redshift, z~~1, analogues of the distant IRX population are identified by first redshifting to z=2 the spectral energy distributions (SEDs) of all sources with secure spectroscopic redshifts in the AEGIS (6488) and the GOODS-North (1784) surveys and then selecting those that qualify as IRX sources at that redshift. A total of 19 galaxies are selected. The mean redshift of the sample is z~~1. We do not find strong evidence for Compton thick QSOs in the sample. For nine sources with X-ray counterparts, the X-ray spectra are consistent with Compton thin active galactic nucleus (AGN). Only three of them show tentative evidence for Compton thick obscuration. The SEDs of the X-ray undetected population are consistent with starburst activity.2010MNRAS.406..420Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/406/420CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/301 : The DEEP2-DR1 Photometric Catalog (Coil+ 2004)J/ApJ/658/1264 : IR-excess sources in GLIMPSE and MSX (Uzpen+, 2007)J/ApJS/180/102 : AEGIS-X: Chandra deep survey (Laird+, 2009)J/ApJ/634/128 : 16{mu}m imaging around the HDF-N (Teplitz+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/406/420https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/406/420http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/406/420https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/406/420https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/406/420http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/406/420GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/406/420/sample (The sample: physical parameters and X-ray properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/406/420/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/406/420/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/406/420/sample?GETtext/xml+votable180.050000true214.07237552.2106250.0055555555555555566/11252 11424-11425 114282.4016587514425055e-21 5.950631229554308e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/406/420?format=asciiOpticalInfrareddefaultJ/MNRAS/406/420/sampleThe sample: physical parameters and X-ray propertiesrecnoRecord number assigned by the VizieR team.
