Black hole-neutron star binaries with high spins and large mass asymmetries: III. Properties of the ejected material and its electromagnetic signatures
Konrad Topolski, Samuel D. Tootle, Paramvir Singh +2
Compact binary systems consisting of a black hole (BH) and a neutron star (NS) are expected to provide detectable signals both in the gravitational wave and in the electromagnetic…
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…
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-…
A new code for computing differentially rotating neutron stars
Samuel D. Tootle, Terrence Pierre Jacques, Marie Cassing
We present new initial data codes for constructing stationary, axisymmetric equilibrium models of differentially rotating neutron stars in full general relativity within the Frankf…
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…
Combining (post-)Newtonian ideas with quasi-equilibrium (QE) sequence analysis for black hole-neutron star (BHNS) gravitational wave events
Antonio Lanza, Samuel D. Tootle, Andrea Lapi
In this paper we present quasi equilibrium models of black hole-neutron star (BHNS) binaries with mass and spin values compatible with parameter estimates derived from gravitationa…
