A Three-Dimensional Exploration of Magnetic Fields, Rotation, and Shock Revival in a Core-Collapse Supernova Progenitor

Liubov Kovalenko, Evan O'Connor, Haakon Andresen +1

We present three-dimensional hydrodynamic and magnetohydrodynamic core-collapse supernova simulations of a rapidly rotating, high-compactness progenitor to investigate…

Black Hole Supernovae Outcomes Across a Wide Progenitor Range

Oliver Eggenberger Andersen, Evan O'Connor, Liubov Kovalenko +2

Black hole supernovae (BHSNe), the term we use for core-collapse events in which black hole (BH) formation occurs after shock revival but before the explosion is complete, have eme…

The Gravitational-Wave Power Gap in Core-Collapse Supernovae: Insights from 60 Axisymmetric Simulations

Haakon Andresen, Xingzao Li, Aurore Betranhandy +3

We analyse the gravitational-wave emission from 60 two-dimensional core-collapse supernova simulations. The models cover a range of progenitors and equations of state. We focus on…

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…

Physics-driven Explosions of Stripped High-Mass Stars: Synthetic Light Curves and Spectra of Stripped-Envelope Supernovae with Broad Lightcurves

Jing Lu, Brandon L. Barker, Jared Goldberg +5

Stripped-envelope supernovae (SESNe) represent a significant fraction of core-collapse supernovae, arising from massive stars that have shed their hydrogen and, in some cases, heli…
