Flash-X, a multiphysics simulation software instrument
Anshu Dubey, Klaus Weide, Jared O'Neal +28
Flash-X is a highly composable multiphysics software system that can be used to simulate physical phenomena in several scientific domains. It derives some of its solvers from FLASH…
Core-Collapse Supernova Simulations including Neutrino Interactions from the Virial EOS
Evan O'Connor, C. J. Horowitz, Zidu Lin +1
Core-collapse supernova explosions are driven by a central engine that converts a small fraction of the gravitational binding energy released during core collapse to outgoing kinet…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Stellar Mass Black Hole Formation and Multi-messenger Signals from Three Dimensional Rotating Core-Collapse Supernova Simulations
Kuo-Chuan Pan, Matthias Liebendörfer, Sean Couch +1
We present self-consistent, 3D core-collapse supernova simulations of a 40 Msun progenitor model using the isotropic diffusion source approximation for neutrino transport and an ef…
Exploring Fundamentally Three-dimensional Phenomena in High-fidelity Simulations of Core-collapse Supernovae
Evan O'Connor, Sean Couch
The details of the physical mechanism that drives core-collapse supernovae (CCSNe) remain uncertain. While there is an emerging consensus on the qualitative outcome of detailed CCS…
Two Dimensional Core-Collapse Supernova Explosions Aided by General Relativity with Multidimensional Neutrino Transport
Evan O'Connor, Sean Couch
We present results from simulations of core-collapse supernovae in FLASH using a newly-implemented multidimensional neutrino transport scheme and a newly-implemented general relati…
Global Comparison of Core-Collapse Supernova Simulations in Spherical Symmetry
Evan O'Connor, Robert Bollig, Adam Burrows +10
We present a comparison between several simulation codes designed to study the core-collapse supernova mechanism. We pay close attention to controlling the initial conditions and i…
