BHaHAHA: A Fast, Robust Apparent Horizon Finder Library for Numerical Relativity
Zachariah B. Etienne, Thiago Assumpção, Leonardo Rosa Werneck +1
Apparent horizon (AH) finders are essential for characterizing black holes and excising their interiors in numerical relativity (NR) simulations. However, open-source AH finders to…
Ultra-low damping of the translational motion of a composite graphite rod in a magneto-gravitational trap
Connor E. Murphy, Cody Jessup, Tahereh Naderishahab +5
We demonstrate an ultra-low dissipation, one-dimensional mechanical oscillator formed by levitating a millimeter-scale composite graphite rod in a room-temperature magneto-gravitat…
GRHayL: a modern, infrastructure-agnostic, extensible library for GRMHD simulations
Samuel Cupp, Leonardo R. Werneck, Terrence Pierre Jacques +2
Interpreting multimessenger signals from neutron stars and black holes requires reliable general relativistic magnetohydrodynamics (GRMHD) simulations across rapidly evolving high-…
Gravitational-Wave Signatures of Massive Black Hole Formation
Bernard J. Kelly, Sarah Gossan, Leonardo R. Werneck +5
Direct-collapse black holes (DCBHs) are an important component of the massive black hole population of the early universe, and their formation and early mergers will be prominent i…
General relativistic hydrodynamics code for dynamical spacetimes with curvilinear coordinates, tabulated equations of state, and neutrino physics
Terrence Pierre Jacques, Samuel Cupp, Leonardo R. Werneck +3
Many astrophysical systems of interest to numerical relativity-such as rapidly rotating stars, black hole accretion disks, and core-collapse supernovae-exhibit near-symmetries. The…
superB/NRPy: Scalable, Task-Based Numerical Relativity for 3G Gravitational Wave Science
Nishita Jadoo, Terrence Pierre Jacques, Zachariah B. Etienne
Modern gravitational-wave science demands increasingly accurate and computationally intensive numerical relativity (NR) simulations. The Python-based, open-source NRPy framework ge…
