Relations between integrated and monochromatic luminosities of flat-spectrum radio quasars
Research in Astronomy and Astrophysics, 2011 We employ a sample of 362 flat-spectrum radio quasars (FSRQs) to calculate their integrated luminosities by integrating the spectral energy distribution (SED) constructed with multi-band (radio, IR, optical, UV and X-ray) data. We compare these luminosities with those estimated from monochromatic luminosities by multiplying them by the conventional ...

Synchrotron X-ray Emission from Flat-spectrum Radio Quasars
, 2003 We present new BeppoSAX observations of four flat-spectrum radio quasars (FSRQ) with spectral energy distributions similar to those of high-energy peaked BL Lacs. In one of our sources the BeppoSAX band is dominated by synchrotron emission peaking at ∼ 2 × 1016 Hz, as also shown by its steep (energy index αx ∼ 1.5) spectrum.
