cds-question@unistra.frinfrared-sourcesinfrared-photometryx-ray-sourcesWe have studied the correlation between 2357 Chandra X-ray point sources in a 40x40pc field and ~20000 infrared sources we observed in the corresponding subset of our 2x1.4{deg} Spitzer/IRAC Galactic Center Survey at 3.6-8.0um, using various spatial and X-ray hardness thresholds. The correlation was determined for source separations of less than 0.5", 1", or 2". Only the soft X-ray sources show any correlation with infrared point sources on these scales, and that correlation is very weak. The upper limit on hard X-ray sources that have infrared counterparts is <1.7% (3{sigma}). However, because of the confusion limit of the IR catalog, we only detect IR sources with absolute magnitudes <~1. As a result, a stronger correlation with fainter sources cannot be ruled out. Only one compact IR source, IRS 13, coincides with any of the dozen prominent X-ray emission features in the 3x3pc region centered on Sgr A*, and the diffuse X-ray and IR emission around Sgr A* seems to be anticorrelated on a few-arcsecond scale. We compare our results with previous identifications of near-infrared companions to Chandra X-ray sources.2008ApJ...685..958Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/685/958CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)II/293 : GLIMPSE Source Catalog (I + II + 3D) (IPAC 2008)II/295 : Spitzer IRAC survey of the galactic center (Ramirez+, 2008)J/ApJ/589/225 : Chandra X-ray sources toward Galactic Center (Feigelson+,J/ApJ/613/1179 : X-ray sources in Galactic Center (Muno+, 2004)J/ApJS/181/110 : Galactic center x-ray sources (Muno+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/685/958https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/685/958http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/685/958https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/685/958https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/685/958http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/685/958GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/685/958/table7 (*IR and X-ray sources coinciding within 1" (no physical association implied))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/685/958/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/685/958/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/685/958/table7?GETtext/xml+votable180.050000true266.33191-29.02930.0055555555555555566/288302.0616683193919197e-20 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/685/958?format=asciiX-rayInfrareddefaultJ/ApJ/685/958/table7*IR and X-ray sources coinciding within 1" (no physical association implied)recnoRecord number assigned by the VizieR team.
