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…
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-…
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…
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…
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…
Accelerating Numerical Relativity with Code Generation: CUDA-enabled Hyperbolic Relaxation
Samuel D. Tootle, Leonardo R. Werneck, Thiago Assumpção +2
Next-generation gravitational wave detectors such as Cosmic Explorer, the Einstein Telescope, and LISA, demand highly accurate and extensive gravitational wave (GW) catalogs to fai…
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…
Toward 2D Dynamo Models Calibrated by Global 3D Relativistic Accretion Disk Simulations
Matthew D. Duez, Courtney L. Cadenhead, Zachariah B. Etienne +2
Two-dimensional models assuming axisymmetry are an economical way to explore the long-term evolution of black hole accretion disks, but they are only realistic if the feedback of t…
The Dynamics of Debris Disk Creation in Neutron Star Mergers
Yossef Zenati, Julian Krolik, Leonardo Werneck +4
The detection of GW170817/AT2017gfo inaugurated an era of multimessenger astrophysics, in which gravitational wave and multiwavelength photon observations complement one another to…
Improved Moving-Puncture Techniques for Compact Binary Simulations
Zachariah B. Etienne
To fully unlock the scientific potential of upcoming gravitational wave (GW) interferometers, numerical relativity (NR) simulation accuracy will need to be greatly enhanced. We pre…
Bound Debris Expulsion from Neutron Star Merger Remnants
Yossef Zenati, Julian H. Krolik, Leonardo R. Werneck +4
Many studies have found that neutron star mergers leave a fraction of the stars' mass in bound orbits surrounding the resulting massive neutron star or black hole. This mass is a s…
