ISO continuum observations of quasars
Listed in IVOA Registry (Virtual Observatory)
Eight luminous quasars with -30<M_B_<-27 at z=1.4-3.7 have been observed in the mid- and far-infrared using ISO.
Description
All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ISOPHOT. SEDs (Spectral Energy Distributions) from the UV to far-infrared have been obtained while supplementing ISO observations with photometry in the optical and near-infrared made from the ground within 17 months.
The SEDs are compared with the MED (Mean spectral Energy Distributions) of low-redshift quasars with -27<M_B_<-22. It is shown that our far-infrared observations were limited by confusion noise due to crowded sources.
