Estimating Starburst Supernova Rates Using OSSE Observations M82 and NGC 253

Abstract

We have used the OSSE observations of the starburst galaxies NGC 253 and M82 to obtain upper limits to the Type Ia and Ib supernova rates in these galaxies. Monte Carlo simulations of randomly occurring supernova events in NGC 253 and M82 were performed to evaluate the significance of our upper limit to the 0.847 and 1.238 MeV 56Co gamma-ray line fluxes on the supernova rate from these two galaxies. A set of observations of NGC 253 and M82 by OSSE is suggested in order to maximize the chances of gamma-ray line detection from these sources.
