The radio structure of 45 quasars at z < 1.5

Abstract

Radio maps at 5 GHz with an angular resolution of 1 to 2 arcsec and a dynamic range ≳200:1 are presented for a sample of 45 radio quasars at redshifts between 0.2 and 1.5. The sources were imaged from observations made with the Very Large Array with the aim of investigating the epoch dependence of misalignments and asymmetries in their extended radio structure. Maps of some of the larger radio sources are presented also at a frequency of 1.5 GHz with a typical angular resolution of ~4 arcsec. The radio structure of most of the quasars reported here has been delineated in considerably greater detail than available in the literature.
