Galactic Diffuse Emission: Predictions for AMEGO and e-ASTROGAM

Elena Orlando


Almost 50% of the photons detected by Fermi LAT is of diffuse interstellar origin produced by cosmic-ray interactions on gas and photon fields in the Galaxy. It is believed that this diffuse large-scale interstellar emission extends also at lower energies. We make predictions of this interstellar emission and also on the extended quiet solar emission for the AMEGO and e-ASTROGAM energy range.
