Radio Variability of Radio‐quiet and Radio‐loud Quasars [PDF]

Astrophysical Journal, 2005
The majority of quasars are weak in their radio emission, with flux densities comparable to those in the optical, and energies far lower. A small fraction, about 10%, are hundreds to thousands of times stronger in the radio. Conventional wisdom holds that there are two classes of quasars, the radio quiets and radio louds, with a deficit of sources ...

Radio-loud and radio-quiet quasars observed by EXOSAT [PDF]

Monthly Notices of the Royal Astronomical Society, 1992
We present results from the spectral analysis of EXOSAT data on 31 quasars, 18 radio-loud and 13 radio-quiet. Simple power-law models with fixed (Galactic) absorption give acceptable fits to the spectra obtained in the 2-10 keV band. Using the results from these fits we have compared the distributions of spectral indices α for the radio-loud and radio ...
