General Relativistic Radiation Magnetohydrodynamic Simulations of Black Hole Accretion

In this talk, I will review recent progress in adding radiation physics to global, general relativistic magnetohydrodynamic (GRMHD) simulations of black hole accretion, starting from a purely optically thin treatment, then transitioning to purely optically thick, and finally discussing current treatments that capture the full range of optical depths. Throughout the talkĀ I will show examples of how these various versions of radiation MHD have already been applied to the study of black hole accretion in different regimes.
