Synthesis Observations of Southern Radio Sources at 1410 MHz with the Parkes Interferometer. II. Polarization and Brightness Distributions Across Seven Sources

Abstract

The Parkes two-element interferometer, which provides a maximum resolution of ~ l' arc at a frequency of 1410 MHz, has been used to obtain the distributions of polarization and brightness across seven extended sources. The results seem to be consistent with a previous interpretation in which the magnetic fields of evolved sources are orthogonal to the direction of elongation but those of relatively young sources are parallel to this direction.
