VLA observations of 57 sources in clusters of galaxies.
Abstract
VLA observations of 57 radio sources in the directions of clusters of galaxies are presented. The data include observations of 41 narrow-angle-tail (NAT) sources, nine wide-angle-tail (WAT) sources and seven sources with complex morphology. Twin-jet structure is found in about 75 percent of the NATs. These observations increase the number of NATs for which there are high-sensitivity (root-mean-square noise about 0.1 mJy/beam), high-resolution (about 1 arcsec) maps by about a factor of 10. Contour plots of the sources are presented. Optical finding charts for 25 previously unidentified sources are given. Brief comments on the properties of the individual radio sources are made. Finally, the general characteristics and interesting features of the different subgroups of sources are summarized.
