cds-question@unistra.frquasarsinfrared-photometrysurveysWe present an analysis of the mid-infrared (MIR) and optical properties of type 1 (broad-line) quasars detected by the Spitzer Space Telescope. The MIR color-redshift relation is characterized to z~3, with predictions to z=7. We demonstrate how combining MIR and optical colors can yield even more efficient selection of active galactic nuclei (AGNs) than MIR or optical colors alone. Composite spectral energy distributions (SEDs) are constructed for 259 quasars with both Sloan Digital Sky Survey and Spitzer photometry, supplemented by near-IR, GALEX, VLA, and ROSAT data, where available.2006ApJS..166..470Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/166/470CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/166/470https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/166/470http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/166/470https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/166/470https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/166/470http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/166/470GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/166/470/qsos (SDSS-Spitzer quasar Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/166/470/qsos?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/166/470/qsos?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/166/470/qsos?GETtext/xml+votable180.050000true164.272458358.07705560.0055555555555555565/1517 1519 6/6044 6046 6047 6073 6075 6090 6112 6114 6120 7444 7445 9463 9469 9471 9634 9635 9640 9641 9642 10146 10147 10152 10153 10154 10189 10190 10191 10202 10212 10213 10214 115202.4016587514425055e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/166/470?format=asciiInfrareddefaultJ/ApJS/166/470/qsosSDSS-Spitzer quasar Photometrye_FUVmag?
