A Black Hole is Born: 3D GRMHD Simulation of Black Hole Formation from Core-Collapse
Goni Halevi, Swapnil Shankar, Philipp Mösta +2
We present the first three-dimensional, fully general-relativistic magnetohydrodynamic (3D GRMHD) simulation of a black hole (BH) formed from the collapsed core of a massive star.…

Magnetically-Driven Neutron-Rich Ejecta Unleashed: Global 3D Neutrino-General Relativistic Magnetohydrodynamic Simulations of Collapsars Probe the Conditions for r-process Nucleosynthesis
Danat Issa, Ore Gottlieb, Brian Metzger +5
Collapsars - rapidly rotating stellar cores that form black holes - can power gamma-ray bursts (GRBs) and are proposed to be key contributors to the production of heavy elements in…

Mahakala: a Python-based Modular Ray-tracing and Radiative Transfer Algorithm for Curved Space-times
Aniket Sharma, Lia Medeiros, Chi-kwan Chan +4
We introduce Mahakala, a Python-based, modular, radiative ray-tracing code for curved space-times. We employ Google's JAX framework for accelerated automatic differentiation, which…
