Contour maps at 102· 5 MHz for 12 galactic SNRs of large angular size in the northern sky are presented. The observations were made with an angular resolution of 48' x24' sec(55° - 8) using the BSA telescope of the Lebedev Physical Institute. All sources were mapped in total intensity. Our results indicate that the contribution to the radiation of observed SNRs from swept up cosmic ray electrons is small. The characteristics of the observed sources are discussed.

Nonthermal Radio Emission

The suggestion that the shocks of supernova remnants (SNR's) are cosmic ray acceleration sites dates back more than 40 years. While observations of nonthermal radio emission from SNR shells indicate the ubiquity of GeV cosmic ray production, there is still theoretical debate about whether SNR shocks accelerate particles up to the well-known “knee” in the primary cosmic ray spectrum at ~3,000 TeV. Recent X-ray observations of SN1006 and other SNR's may have provided the missing observational link between SNR shocks and high energy cosmic ray acceleration. We discuss these observations and their interpretation, and summarize our ongoing efforts to find evidence from X-ray observations of cosmic ray acceleration in the shells of other SNR's.
