Search for gamma-ray emission from a galactic supernova with the anticoincidence system of SPI

Abstract

The detection of the very early gamma-emission of a Type Ia supernova (SNIa) could provide a deep insight on the explosion mechanism and nature of the progenitor. However this has not been yet possible as a consequence of the expected low luminosity and the distance at which all the events have occurred up to now. A SNIa occurring in our Galaxy could provide a unique opportunity to perform such measurement. The problem is that the optical flux would probably be so attenuated by interstellar extinction that would prevent triggering the observations with gamma-spectrometers at the due time. In this paper we analyse the possibility of using the anticoincidence system (ACS) of the spectrometer SPI on board of the INTEGRAL space observatory for detecting the early gamma-ray emission of a SNIa as a function of the explosion model and distance as well as of pointing direction. Our results suggest that such detection is possible at about 6 - 12 days after the explosion and, at the same time, we can discard missing any hidden explosion during the lifetime of INTEGRAL.
