Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION
SEARCH FOR EVIDENCE OF SHOCK ACCELERATION IN LMC TYPE IA SNRS
ABSTRACT
We propose deep reobservations of two supernova remnants in the LMC, N103B and 0519-69.0. Both of these are the products of Type Ia explosions. The primary goal of the observations is to search for evidence of a hard tail, indicative of shock acceleration of cosmic rays to very high energy, as observed in the ASCA spectrum of the Galactic Type Ia remnant SN1006. A secondary goal is a careful characterization of the thermal emission, and a a quantitative comparison of the inferred metal abundances with those expected from models of explosive nucleosythesis in Type Ia supernovae.
