cds-question@unistra.frquasarsredshiftedinfrared-photometryx-ray-sourcessurveysvisible-astronomysloan-photometryUsing the public data from the Herschel wide-field surveys, we study the far-infrared properties of optical-selected quasars from the Sloan Digital Sky Survey. Within the common area of ~172deg^2^, we have identified the far-infrared counterparts for 354 quasars, among which 134 are highly secure detections in the Herschel 250um band (signal-to-noise ratios >=5). This sample is the largest far-infrared quasar sample of its kind, and spans a wide redshift range of 0.14<=z<=4.7. Their far-infrared spectral energy distributions, which are due to the cold-dust components within the host galaxies, are consistent with being heated by active star formation. In most cases (>~80%), their total infrared luminosities as inferred from only their far-infrared emissions (L_IR_^(cd)^) already exceed 10^12^L_{sun}_, and thus these objects qualify as ultra-luminous infrared galaxies. There is no correlation between L_IR_^(cd)^ and the absolute magnitudes, the black hole masses or the X-ray luminosities of the quasars, which further support that their far-infrared emissions are not due to their active galactic nuclei. A large fraction of these objects (>~50%-60%) have star-formation rates >~300M_{sun}_/yr. Such extreme starbursts among optical quasars, however, is only a few percent. This fraction varies with redshift, and peaks at around z~2. Among the entire sample, 136 objects have secure estimates of their cold-dust temperatures (T), and we find that there is a dramatic increasing trend of T with increasing L_IR_^(cd)^. We interpret this trend as the envelope of the general distribution of infrared galaxies on the (T, L_IR_^(cd)^) plane.2015ApJ...811...58Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/811/58CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/270 : SDSS quasar catalog: tenth data release (Paris+, 2014)VIII/95 : Herschel Multi-tiered Extragalactic Survey (Oliver+, 2012)IX/45 : The Chandra Source Catalog, Release 1.1 (Evans+ 2012)VII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)II/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/ApJS/210/22 : Herschel Stripe 82 survey (HerS) 1st catalog (Viero+, 2014)J/ApJ/773/14 : BOSS: quasar luminosity function (Ross+, 2013)J/ApJ/757/13 : IR SEDs of 24um z~0.3-3 galaxies (Sajina+, 2012)J/ApJS/199/3 : The quasars MMT-BOSS pilot survey (Ross+, 2012)J/MNRAS/415/2336 : Herschel-ATLAS Science Demonstration Catalog (Rigby+, 2011)J/A+A/532/A90 : PACS Evolutionary Probe (PEP-DR1) catalogs (Lutz+, 2011)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/A+A/495/691 : Multifrequency cat. of blazars Roma-BZCAT (Massaro+, 2009)J/MNRAS/380/199 : SCUBA Half-Degree Extragalactic Survey.
