Toward Five-dimensional Core-collapse Supernova Simulations
Christian Y. Cardall, Alexei O. Razoumov, Eirik Endeve +2
The computational difficulty of six-dimensional neutrino radiation hydrodynamics has spawned a variety of approximations, provoking a long history of uncertainty in the core-collap…
Conservative special relativistic radiative transfer for multidimensional astrophysical simulations: motivation and elaboration
Christian Y. Cardall, Eric J. Lentz, Anthony Mezzacappa
Many astrophysical phenomena exhibit relativistic radiative flows. While velocities in excess of can occur in these systems, it has been common practice to approximat…
Fully Threaded Transport Engine: New Method for Multi-Scale Radiative Transfer
A. O. Razoumov, C. Y. Cardall
A new, very fast method for 3D radiative transfer on fully threaded grids with arbitrarily high angular resolution is presented. The method uses completely cell-based discretizatio…
Supernova neutrino challenges
Christian Y. Cardall
A principal `supernova neutrino challenge' is the computational difficulty of six-dimensional neutrino radiation hydrodynamics. The variety of resulting approximations has provoked…
