摘要
VLA observations of 11 wide-angle tailed radio sources are presented. The total intensity 20 cm image of each source is shown at the highest resolution which does not resolve out the extended structure. Images of radio contours overlaid on the CCD images of the parent galaxies are presented. The sources were also imaged at 6 cm. Spectral index information was obtained and is presented as a function of distance along the tails for each source. The magnetic fields, total energies, and pressures derived from a minimum pressure analysis are also presented as functions of distance along the tails. The polarization of the sources is discussed.
