An Approach to Neutrino Radiative Transfer in Supernova Simulations

Neutrinos dominate the energetics of core-collapse supernovae, and are believed to play an important role in driving the explosion. The development of a spatially multidimensional neutrino radiative transfer code is a key part of the Terascale Supernova Initiative, a multi-year effort aimed at understanding the supernova explosion mechanism through supercomputer simulations. I will describe the conservative formulations of general relativistic radiative transfer we have developed for this application, and the algorithm we are implementing in our parallel code.
