Approximating General Relativity in Core-Collapse Supernova Simulations
Steven A. Fromm, Vassilios Mewes, O. E. Bronson Messer +3
We present formulations of effective potentials suitable for approximating general relativistic effects in Newtonian simulations of core-collapse supernovae. Assuming a spherically…

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…

Relativistic gas accretion onto supermassive black Hole binaries from inspiral through merger
Lorenzo Ennoggi, Manuela Campanelli, Yosef Zlochower +8
Accreting supermassive black hole binaries are powerful multimessenger sources emitting both gravitational and EM radiation. Understanding the accretion dynamics of these systems a…
