Abstract:

The emission of our Universe is well characterized at most wavelengths, but a gap remains at MeV energies. This is an energy range where nuclear decays from type Ia supernovae (SNIa), emission from radio-loud and radio-quiet active galactic nuclei (AGN) and potentially dark matter interaction can each contribute to the MeV background. An all-sky MeV mission like AMEGO will allow us to measure the intensity and the angular fluctuations of the MeV background. This will allow us to constrain models of SNIa formation, the evolution of radio-loud and radio-quiet AGN, the growth of the most massive black holes and to constrain the cross-section for dark matter interaction.
