Scientific paper

The results of theoretical and observational studies suggest that, immediately downstream of the forward shock, a significant fraction of the energy density in young, shell-type supernova remnants is in the form of nonthermal particles. The pressure of the nonthermal particles modifies the structure of a shock. There are at least three potentially observable consequences: (1) The temperature of the thermal particles in the shock-heated gas is reduced. (2) The effective compression ratio of the shock is increased. (3) The spectrum of the nonthermal particles flattens with increasing energy. We describe some of the results for each of these three effects and discuss the implications for cosmic-ray acceleration. GEA is supported by the contract SV3-73016 between MIT and the Smithsonian Astrophysical Observatory.
