Radio intensity and polarization distributions of quasars at three frequencies.
Abstract
Measurements have been made with the Westerbork Synthesis Radio Telescope of 114 quasars at 4995 MHz, 32 at 1415 MHz, and 22 at 610 MHz. All had known redshifts and 86 were resolved at 4995 MHz. Parameters characterizing the structures are tabulated. For the larger sources (>2.5 beam lengths) the total intensity and where appropriate the polarization distributions are illustrated. A search at 610 MHz for halo emission around eight strong quasars had negative results to a level of about 1 percent. Key words: quasars - radio structures - polarizations
