General-relativistic Radiation Transport Scheme in Gmunu. I. Implementation of Two-moment-based Multifrequency Radiative Transfer and Code Tests

We present the implementation of a two-moment-based general-relativistic multigroup radiation transport module in the G eneral-relativistic mu ltigrid nu merical ( Gmunu ) code. On top of solving the general-relativistic magnetohydrodynamics and the Einstein equations with conformally flat approxima...
