Abstract The explosion mechanism associated with thermonuclear supernovae (SNIa) is still a matter of debate. However, there is a wide agreement that high amounts of radioactive nuclei are produced during these events and they are expected to be strong gamma-ray emitters able to be used as diagnostic tools of the explosion. Detailed numerical simulations have convincingly shown that SPI and IBIS can be succesfully used to discriminate among the explosion mechanisms provided the supernova occurs at an appropriate distance. These tests include the temporal evolution of the lines as well as the value of the relative intensities, the properties of the continuum and the linewidths. The data collected by the X-ray and optical monitors (JEM-X and OMC) will also be analysed, as they can provide additional information about the nature of the presupernova system and the spatial heterogeneities of the ejecta.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
