Abstract:
We constructed a sample of 185 flat-spectrum radio quasars (FSRQs) by
cross-correlating Shen et al.'s (2006MNRAS.369.1639S 2006MNRAS.369.1639S) Sloan Digital
Sky Survey Data Release 3 (SDSS DR3) X-ray quasar sample with the
Faint Images of the Radio Sky at Twenty Centimeters (FIRST) and Green
Bank 6-cm survey (GB6) radio catalogues. From the spectral energy
distribution (SED) constructed using multi-band (radio, UV, optical,
infrared and X-ray) data, we derived the synchrotron peak frequency
and peak luminosity. The black hole mass MBH and the broad-line region
(BLR) luminosity (then the bolometric luminosity Lbol) were obtained
by measuring the linewidth and strength of broad emission lines from
SDSS spectra. We define a subsample of 118 FSRQs for which non-thermal
jet emission is thought to dominate over thermal emission from the
accretion disc and host galaxy.
