Title: Simulations of core collapse supernovae in one and two dimensions using multigroup neutrino transport

Simulations of core collapse supernovae in one and two dimensions using multigroup neutrino transport In one dimension, we present results from comparisons of stationary state multi-group flux-limited diffusion and Boltzmann neutrino transport, focusing on quantities central to the postbounce shock reheating. In two dimensions, we present results from simulations that couple one-dimensional multigroup flux-limited diffusion to two- dimensional (PPM) hydrodynamics.
