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…
Wave Optics Effects from Gravitational Wave Propagation Through Dark Matter Halos
Annamalai P. Shanmugaraj, Roland Haas, Erik Schnetter +1
Gravitational wave (GW) propagation is usually studied under the geometric optics approximation. But when GWs propagate through structures of sizes similar to their wavelength, thi…
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…
GPU-accelerated Subcycling Time Integration with the Einstein Toolkit
Liwei Ji, Roland Haas, Yosef Zlochower +3
Adaptive Mesh Refinement (AMR) with subcycling in time enables different grid levels to advance using their own time steps, ensuring finer grids employ smaller steps for accuracy w…
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…
General Relativistic Stability and Gravitational Wave Content of Rotating Triaxial Neutron Stars
Yufeng Luo, Antonios Tsokaros, Roland Haas +1
Triaxial neutron stars can be sources of continuous gravitational radiation detectable by ground-based interferometers. The amplitude of the emitted gravitational wave can be great…
