Description
The diffuse gamma-ray background (DGRB) measured by various telescopes spans over a wide energy range from keV to around TeV. In the energy range (100 MeV-820 GeV), the DGRB can be explained by sources such as blazars and star forming galaxies. Whereas in the lower energies up to around 0.3 MeV, the dominant sources are found to be active galactic nuclei and Seyfert galaxies. However, in the intermediate MeV energies (MeV DGRB), the sources in addition to the supernovae are not yet fully explored due to lack of MeV observation data. In this work, we explore the contribution of gamma-ray emission from r-process nucleosynthesis in Kilonovae to the MeV DGRB. Finally, we analyse the potential measurement of this MeV DGRB Kilonovae signal with future MeV missions.
