Abstract

A series of polarimetric observations at 2.7 and 5 GHz were made with a 64-m telescope for a total of 20 supernoval remnants (SNRs) in order to obtain information with a resolution of 8.4 arcmin. The data are used to plot maps of the distribution of magnetic field orientation, Faraday rotation, and depolarization ratio for the 20 sources considered. One effect is an apparent evolutionary separation of magnetic field patterns into two groups: (1) the young SNRs clearly show radially oriented fields, implying a stretching of the field lines as the remnant rapidly expands; and (2) some of the very old remnants show magnetic field patterns tangential to the brightest parts of the SNR shell, suggesting a possible compression of the surrounding field. In all sources the mean degree of polarization was generally low. Generally, neither the Faraday rotation nor the depolarization showed any correlation with the observed total intensity.
