Impacts of Multidimensional Progenitor Perturbations on Core-Collapse Supernova Explosions
Chien-Hui Chen, Eric J. Lentz, W. Raphael Hix +3
Numerical studies of core-collapse supernovae have demonstrated the importance of non-radial motions in pre-collapse progenitors on the explosion outcome. We use the CHIMERA neutri…

thornado+Flash-X: A Hybrid DG-IMEX and Finite-Volume Framework for Neutrino-Radiation Hydrodynamics in Core-Collapse Supernovae
Eirik Endeve, Vassilios Mewes, J. Austin Harris +15
We present neutrino-transport algorithms implemented in the toolkit for high-order neutrino-radiation hydrodynamics (thornado) and their coupling to self-gravitating hydrodynamics…

Gravitational Waves as a Probe of Core Collapse Supernova Progenitor Structure
R. Daniel Murphy, Elle Brinkman, Colter J. Richardson +5
We present the gravitational wave predictions from two-dimensional core collapse supernova (CCSN) simulations initiated from two nearly identical progenitors that have significantl…
