The imprint of individual neutron star spins on ejecta, -process nucleosynthesis, and kilonovae in binary neutron star mergers
Beyhan Karakas, Rahime Matur, David Radice +2
To leading order, the gravitational-wave (GW) signal from binary neutron stars depends on the individual spins, and , only through the effective spin parameter $χ_{\rm e…
A Reproducible Black Hole-Neutron Star Merger Gallery Example for the Einstein Toolkit
Rahime Matur, Beyhan Karakaş, Roland Haas +3
Black hole-neutron star mergers are important sources of gravitational waves and potential electromagnetic counterparts, but publicly available numerical relativity configurations…
A resistive MHD module in the GPU-accelerated GRMHD code GRaM-X
Sara Azizi, Swapnil Shankar, Philipp Mösta +2
Relativistic macroscopic plasma dynamics can be described by general-relativistic magnetohydrodynamics. In many high-energy astrophysical settings, such as the interior dynamics of…
Gravitational waves from magnetorotational core-collapse supernovae using 3D GRMHD simulations: effect of rotation and magnetic fields
Sophia C. Schnauck, Swapnil Shankar, Philipp Mösta +2
We investigate the gravitational wave emission for 10 supernova progenitors from magnetorotational core-collapse to the supernova explosion using fully three-dimensional dynamical-…
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.…
3D full-GR simulations of magnetorotational core-collapse supernovae on GPUs: A systematic study of rotation rates and magnetic fields
Swapnil Shankar, Philipp Mösta, Roland Haas +1
We present a series of fully three-dimensional, dynamical-spacetime general relativistic magnetohydrodynamics (GRMHD) simulations of core-collapse supernovae (CCSNe) for a progenit…
AsterX: a new open-source GPU-accelerated GRMHD code for dynamical spacetimes
Jay V. Kalinani, Liwei Ji, Lorenzo Ennoggi +10
We present AsterX, a novel open-source, modular, GPU-accelerated, fully general relativistic magnetohydrodynamic (GRMHD) code designed for dynamic spacetimes in 3D Cartesian coordi…
