Abstract

The thesis reports the reduction and analysis of Very Large Array snapshot observations at 6 cm with the A and C arrays of 192 and 192 + 89 radio sources associated with quasars. The sample includes all of the candidates for the complete samples of radio-loud quasars discussed by Wills and Lynds (1978). The routine reduction included two passes of phase self-calibration. Maps were made with image size of 512 x 512. The A (C) array maps have 0.1 (1.3) arcsec cell sizes, with 0.1 to 0.2 (0.2 to 0.4) mJy/Beam rms noise and dynamic ranges of a few thousand. Radio positions and flux densities were measured, and contour maps were plotted. A statistically significant excess of serendipitous radio sources was found within 2 arcmin of the quasars observed in the C array. These serendipitous sources could be radio galaxies at the quasar redshifts and the excess might arise from rich clusters of galaxies associated with the quasars.
