A new versatile code for gamma-ray Monte-Carlo radiative transfer

ABSTRACT Ongoing MeV telescopes such as INTEGRAL/SPI and Fermi/GBM, proposed including the recently accepted COSI e-ASTROGAM AMEGO missions, provide another window in understanding transients. Their signals contain information about stellar explosion mechanisms their corresponding nucleosynthesis of short-lived radioactive isotopes. This raises need a radiative transfer code which may efficiently explore different types astrophysical γ-ray sources dependence on model parameters input physics. In view this, we present our new Monte-Carlo Radiative Transfer python. The synthesizes spectra light curves suitable for modelling supernova ejecta, C+O novae, O+Ne Type Ia core-collapse supernovae. We test extensively reproducing results consistent with analytic models. also compare similar models literature discuss how depends selected physics setting.
