Gravitational waveforms of binary neutron star inspirals using post-Newtonian tidal splicing
Kevin Barkett, Yanbei Chen, Mark A. Scheel +1
The tidal deformations of neutron stars within an inspiraling compact binary alter the orbital dynamics, imprinting a signature on the gravitational wave signal. Modeling this sign…
Numerical relativity simulation of GW150914 beyond general relativity
Maria Okounkova, Leo C. Stein, Jordan Moxon +2
We produce the first astrophysically-relevant numerical binary black hole gravitational waveform in a higher-curvature theory of gravity beyond general relativity. We simulate a sy…
Spectral Cauchy-characteristic extraction of the gravitational wave news function
Kevin Barkett, Jordan Moxon, Mark A. Scheel +1
We present an improved spectral algorithm for Cauchy-characteristic extraction and characteristic evolution of gravitational waves in numerical relativity. The new algorithms impro…
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…
Unequal Mass Binary Neutron Star Simulations with Neutrino Transport: Ejecta and Neutrino Emission
Trevor Vincent, Francois Foucart, Matthew D. Duez +4
We present twelve new simulations of unequal mass neutron star mergers. The simulations were preformed with the SpEC code, and utilize nuclear-theory based equations of state and a…
Numerical binary black hole collisions in dynamical Chern-Simons gravity
Maria Okounkova, Leo C. Stein, Mark A. Scheel +1
We produce the first numerical relativity binary black hole gravitational waveforms in a higher-curvature theory beyond general relativity. In particular, we study head-on collisio…
All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1186
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gra…
Surrogate models for precessing binary black hole simulations with unequal masses
Vijay Varma, Scott E. Field, Mark A. Scheel +5
Only numerical relativity simulations can capture the full complexities of binary black hole mergers. These simulations, however, are prohibitively expensive for direct data analys…
Testing the no-hair theorem with GW150914
Maximiliano Isi, Matthew Giesler, Will M. Farr +2
We analyze gravitational-wave data from the first LIGO detection of a binary black-hole merger (GW150914) in search of the ringdown of the remnant black hole. Using observations be…
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…
Black hole ringdown: the importance of overtones
Matthew Giesler, Maximiliano Isi, Mark Scheel +1
It is possible to infer the mass and spin of the remnant black hole from binary black hole mergers by comparing the ringdown gravitational wave signal to results from studies of pe…
On the properties of the massive binary black hole merger GW170729
Katerina Chatziioannou, Roberto Cotesta, Sudarshan Ghonge +53
We present a detailed investigation into the properties of GW170729, the gravitational wave with the most massive and distant source confirmed to date. We employ an extensive set o…
