cds-question@unistra.frquasarsinfrared-photometryvisible-astronomysloan-photometryWe use the Spitzer Space Telescope Enhanced Imaging Products and the Spitzer Archival Far-InfraRed Extragalactic Survey to study the spectral energy distributions (SEDs) of spectroscopically confirmed type 1 quasars selected from the Sloan Digital Sky Survey (SDSS). By combining the Spitzer and SDSS data with the Two Micron All Sky Survey, we are able to construct a statistically robust rest-frame 0.1-100{mu}m type 1 quasar template. We find that the quasar population is well-described by a single power-law SED at wavelengths less than 20{mu}m, in good agreement with previous work. However, at longer wavelengths, we find a significant excess in infrared luminosity above an extrapolated power-law, along with significant object-to-object dispersion in the SED. The mean excess reaches a maximum of 0.8dex at rest-frame wavelengths near 100{mu}m.2013ApJ...768...13Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/768/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/MNRAS/434/3104 : QSOs SED shapes from optical to NIR (Hao+, 2013)J/ApJS/206/4 : SED & bolometric corrections for QSOs (Krawczyk+, 2013)J/ApJ/757/51 : FIRST-2MASS dust-reddened QSO spectra (Glikman+, 2012)J/ApJ/757/13 : IR SEDs of 24um z~0.3-3 galaxies (Sajina+, 2012)J/ApJ/716/530 : Mid-IR variability from the SDWFS (Kozlowski+, 2010)J/AJ/139/390 : SDSS-DR7 optically selected BL Lac objects (Plotkin+, 2010)J/AJ/136/2373 : Type 2 quasars from SDSS (Reyes+, 2008)J/MNRAS/386/1252 : SWIRE/SDSS quasars (Hatziminaoglou+, 2008)J/ApJ/666/806 : SED of Spitzer quasars (QUEST) (Netzer+, 2007)J/ApJ/663/81 : SED of hard X-ray selected AGN in XMDS (Polletta+, 2007)J/ApJS/166/470 : SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)J/ApJS/95/1 : Atlas of Quasar Energy Distributions (Elvis+ 1994)http://irsa.ipac.caltech.edu/data/SPITZER/Enhanced/SEIP : Spitzer Enhancedhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/768/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/768/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/768/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/768/13https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/768/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/768/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/768/13/table2 (Spitzer Archival FIR Extragalactic Survey (SAFIRES) photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/768/13/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/768/13/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/768/13/table2?GETtext/xml+votable180.050000true157.55657.5080.0055555555555555565/1511 1517 1519 2286 2287 2628 2629 6/6065 6067 6073 6075 6090 6112 6113 6114 6120 7444 7445 9135 9194 10501 105211.0763920601544068e-21 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/768/13?format=asciiOpticalInfrareddefaultJ/ApJ/768/13/table2Spitzer Archival FIR Extragalactic Survey (SAFIRES) photometryrecnoRecord number assigned by the VizieR team.
