Understanding Core-Collapse Supernovae using COSI

For over 50 years, multi-messenger diagnostics, including dust grains, neutrinos, and electromagnetic observations, have provided crucial insights into core-collapse supernovae. The SN 1987A event in the Large Magellanic Cloud highlighted the significance of these observations, emphasizing their potential to probe various aspects of supernova physics and progenitor evolution, ultimately enhancing our understanding of more distant and less-diagnosed supernovae. The upcoming Compton Spectrometer and Imager (COSI) mission promises a new era in gamma-ray astronomy, delving into stellar nucleosynthesis. Our work involves simulating COSI observations with MEGAlib and comparing them to realistic backgrounds to gauge sensitivity and gamma-ray detections of the initial supernova explosions. The aim is to ensure the COSI team is ready to detect and characterize these sources at launch in 2027, contributing to a broader multi-messenger context to enable a deeper understanding of the physics that underlies these events.
