Nonlinearities in Black Hole Ringdowns
Keefe Mitman, Macarena Lagos, Leo C. Stein +11
The gravitational wave strain emitted by a perturbed black hole (BH) ringing down is typically modeled analytically using first-order BH perturbation theory. In this Letter we show…
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 high-order shock capturing discontinuous Galerkin-finite-difference hybrid method for GRMHD
Nils Deppe, François Hébert, Lawrence E. Kidder +1
We present a discontinuous Galerkin-finite-difference hybrid scheme that allows high-order shock capturing with the discontinuous Galerkin method for general relativistic magnetohy…
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…
High-accuracy waveforms for black hole-neutron star systems with spinning black holes
Francois Foucart, Alexander Chernoglazov, Michael Boyle +10
The availability of accurate numerical waveforms is an important requirement for the creation and calibration of reliable waveform models for gravitational wave astrophysics. For b…
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…
The SXS Collaboration catalog of binary black hole simulations
Michael Boyle, Daniel Hemberger, Dante A. B. Iozzo +37
Accurate models of gravitational waves from merging black holes are necessary for detectors to observe as many events as possible while extracting the maximum science. Near the tim…
What does a binary black hole merger look like?
Andy Bohn, William Throwe, François Hébert +4
We present a method of calculating the strong-field gravitational lensing caused by many analytic and numerical spacetimes. We use this procedure to calculate the distortion caused…
