Radio and X-ray emission in radio-selected quasars.
Abstract
In order to investigate the physical relationship between radio and X-ray emission in quasars, the authors have observed with the Very Large Array 31 radio-loud quasars and a comparable number of radio-quiet quasars. The sample was selected to include quasars with known X-ray luminosities but poorly-known radio properties. Maps with polarization data of 15 extended radio-loud quasars at 20 cm and 6 cm are presented. They show jet magnetic fields to be aligned along the source axis while lobe fields have misaligned orientations. The authors have sought statistical associations between X-ray luminosity and extended radio luminosity, spectrum, morphology, and size in an extended sample of 44 radio-loud quasars. Only one statistically significant correlation, between X-ray and 178-MHz power, is found.
