Abstract
VLA maps of total intensity and fractional polarization at λ3.6 cm are presented for 11 radio galaxies, part of a sample of 29 nearby radio galaxies with P178 > 1.5 × 1025 W Hz−1 sr−1. Ten have classical double structure. The hotspots in all of these are well resolved. We have discovered a one-sided jet in 3C 135, as well as imaging the known jets in 3C 98, 111 and 445 at high resolution. There are also possible jets in five of the remaining six classical doubles. The eleventh object, 3C 15, is well imaged here for the first time. It is dominated by a bright jet, and a weak counterjet is also detected. We point out some of the more common patterns in the structure of the hotspot complexes in our sample, and summarize the frequency with which jets and the various types of hotspot complex are found.Keywords
