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…

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…

Grazing Collisions of Black Holes via the Excision of Singularities

Steve Brandt, Randall Correll, Roberto Gomez +10

We present the first simulations of non-headon (grazing) collisions of binary black holes in which the black hole singularities have been excised from the computational domain. Ini…

The Evolution of Distorted Rotating Black Holes I: Methods and Tests

Steven R. Brandt, Edward Seidel

We have developed a new numerical code to study the evolution of distorted, rotating black holes. We discuss the numerical methods and gauge conditions we developed to evolve such…
