ONE-DIMENSIONAL POLARIZATION DISTRIBUTIONS OVER FOUR SUPERNOVA REMNANTS AT 1418 MHZ,
Abstract
Distributions of the linearly polarized radiation at a frequency of 1418 MHz from the four supernova remnants 3C 10 (Tycho's supernova), Taurus A (Crab Nebula), 3C358 (Kepler's supernova), and Cassiopeia A have been determined by synthesizing a fan beam whose small dimension is along a circle of constant declination. In addition, extremely low upper limits have been placed on the net degree of circular polarization in the integrated radiation from Tau A, 3C358, and Cas A. For the latter two sources, no smaller circularly polarized regions were found within the source dimensions using a resolution of better than 1'. Upper limits to the magnetic field strengths, modified by geometrical factors have also been calculated. (Author)
