A VLA Study of 15 3CR Radio Galaxies

Abstract

We present VLA radio maps in total intensity and polarization at 1.4, 4.9 and 8.4 GHz of fifteen 3CR radio galaxies for which good maps showing the large-scale radio structure have not previously been available. Previously unknown cores are detected in several sources and a bright one-sided jet in 3C 287.1 is mapped for the first time; several other jet-like features are also imaged. Total and core fluxes are tabulated and radio core positions are listed and compared to optical positions. The galaxy at the optical position listed for 3C 169.1 is found to lie farther from the radio core position than another dimmer, bluer galaxy. We discuss individual sources in some detail.
