cds-question@unistra.frquasarsinfrared-photometryredshiftedWe present a mid-infrared (MIR) analysis of 35 quasars with spectroscopic redshifts selected from the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE). We discuss their optical and MIR colors and show that these quasars occupy well-defined regions in MIR color-color space. We examine the issue of type 1 active galactic nuclei candidate selection in detail and propose new selection methods based on MIR colors. The available multiband data allow us to construct two new, well-sampled quasar templates, covering wavelengths from the ultraviolet to the MIR.2005AJ....129.1198Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/1198CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/255 : SWIRE ELAIS N1 Source Catalogs (Surace+, 2004)http://www.sdss.org : SDSS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/1198https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/1198http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/1198https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/1198https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/1198http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/1198GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/129/1198/table1 (Positions, redshifts, optical magnitudes, and aperture fluxes for the 35 spectroscopically confirmed quasars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/1198/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/1198/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/1198/table1?GETtext/xml+votable180.050000true239.135541754.72663890.005555555555555556Cone search capability for table J/AJ/129/1198/table4 (2MASS Vega magnitudes, ISO fluxes (from Vaccari et al. 2005MNRAS.358..397V), radio fluxes, and related errors (whenever available) for the quasars with near-IR and/or 15{mu}m and/or radio counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/1198/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/1198/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/1198/table4?GETtext/xml+votable180.050000true239.900541754.70105560.0055555555555555566/10146 10147 10152 10153 10154 11349 11520 115228.650015785639275e-20 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/129/1198?format=asciiOpticalInfrareddefaultJ/AJ/129/1198/table1Positions, redshifts, optical magnitudes, and aperture fluxes for the 35 spectroscopically confirmed quasarsrecnoRecord number assigned by the VizieR team.
