Radioactive Decay in Core-Collapse Supernovae
High energy emission from supernovae provide a direct window into the quantity and distribution of radioactive elements produced in these explosions. This information has proven to be of tremendous importance in inferring details of the shock evolution in core-collapse supernovae. This chapter highlights the theoretical advances in core-collapse explosion simulations which have been motivated by the many surprises in γ-ray observations. In particular, the presence of asymmetries in the explosion, as inferred from the high energy spectra, are emphasized. Recent simulations combining supernova explosion calculations with 3D Monte Carlo γ-ray transport are presented. The diagnostic capability of the high energy emission to distinguish mild explosion asymmetries is demonstrated.
