Description

We perform multi-dimensional, time-dependent radiation transfer simulations for hard X-ray and γ -ray emissions, following radioactive decays of 56Ni and 56Co, for two-dimensional delayed-detonation models of Type Ia supernovae (SNe Ia). The synthetic spectra and light curves are compared with the sensitivities of current and future observatories for an exposure time of 106 s. The non-detection of the γ -ray signal from SN 2011fe at 6.4 Mpc by SPI on board INTEGRAL places an upper limit on...[Show more]
