A Comparison of Boltzmann and Multigroup Flux-Limited Diffusion Neutrino Transport During the Postbounce Shock Reheating Phase in Core Collapse Supernovae
Bronson Messer, Anthony Mezzacappa, Steve Bruenn +1
We compare Newtonian three-flavor multigroup Boltzmann (MGBT) and (Bruenn's) multigroup flux-limited diffusion (MGFLD) neutrino transport in postbounce core collapse supernova envi…

An Investigation of Neutrino-Driven Convection and the Core Collapse Supernova Mechanism Using Multigroup Neutrino Transport
A. Mezzacappa, A. C. Calder, S. W. Bruenn +4
We investigate neutrino-driven convection in core collapse supernovae and its ramifications for the explosion mechanism. We begin with an ``optimistic'' 15 solar mass precollapse m…

Deciphering Core Collapse Supernovae: Is Convection the Key? I. Prompt Convection
A. Mezzacappa, A. C. Calder, S. W. Bruenn +4
We couple two-dimensional hydrodynamics to detailed one-dimensional multigroup flux-limited diffusion neutrino transport to investigate prompt convection in core collapse supernova…
