Comparing Remnant Properties from Horizon Data and Asymptotic Data in Numerical Relativity

Dante A. B. Iozzo, Neev Khera, Leo C. Stein +10

We present a new study of remnant black hole properties from 13 binary black hole systems, numerically evolved using the Spectral Einstein Code. The mass, spin, and recoil velocity…

Axisymmetric Hydrodynamics in Numerical Relativity Using a Multipatch Method

Jerred Jesse, Matthew D. Duez, Francois Foucart +7

We describe a method of implementing the axisymmetric evolution of general-relativistic hydrodynamics and magnetohydrodynamics through modification of a multipatch grid scheme. In…

Late-time post-merger modeling of a compact binary: effects of relativity, r-process heating, and treatment of transport effects

Milad Haddadi, Matthew D. Duez, Francois Foucart +8

Detectable electromagnetic counterparts to gravitational waves from compact binary mergers can be produced by outflows from the black hole-accretion disk remnant during the first t…

A comparison of momentum transport models for numerical relativity

Matthew D. Duez, Alexander Knight, Francois Foucart +6

The main problems of nonvacuum numerical relativity, compact binary mergers and stellar collapse, involve hydromagnetic instabilities and turbulent flows, so that kinetic energy at…

Smooth equations of state for high-accuracy simulations of neutron star binaries

Francois Foucart, Matthew D. Duez, Alana Gudinas +4

High-accuracy numerical simulations of merging neutron stars play an important role in testing and calibrating the waveform models used by gravitational wave observatories. Obtaini…

Implementation of Monte-Carlo transport in the general relativistic SpEC code

Francois Foucart, Matthew D. Duez, Francois Hebert +4

Neutrino transport and neutrino-matter interactions are known to play an important role in the evolution of neutron star mergers, and of their post-merger remnants. Neutrinos cool…
