Abstract: |
To be launched in 2027 as NASA Small Explorer Mission, the Compton Spectrometer and Imager (COSI) will image the entire soft gamma-ray sky in the 0.2”Ŗ5.0 MeV range. COSI is designed for the primary goals of uncovering the source of Galactic positrons, imaging diffuse emission from stellar nucleosynthesis, and performing polarization studies of gamma-ray bursts and compact objects. With unprecedented sensitivity in the MeV range and exquisite energy resolution, COSI is expected to provide advances well beyond its prime goals. In this presentation I will give an overview of the future studies enabled by COSI, with emphasis on how COSI can give insights on the nature of dark matter, leading to improvements of the current dark matter bounds in its energy range. |
