Persistent gravitational wave observables: Nonlinear plane wave spacetimes
Éanna É. Flanagan, Alexander M. Grant, Abraham I. Harte +1
In the first paper in this series, we introduced "persistent gravitational wave observables" as a framework for generalizing the gravitational wave memory effect. These observables…
Asymptotic symmetries and charges at spatial infinity in general relativity
Kartik Prabhu, Ibrahim Shehzad
We analyze the asymptotic symmetries and their associated charges at spatial infinity in -dimensional asymptotically-flat spacetimes. We use the covariant formalism of Ashtekar…
Angular momentum at null infinity in Einstein-Maxwell theory
Béatrice Bonga, Alexander M. Grant, Kartik Prabhu
On Minkowski spacetime, the angular momentum flux through null infinity of Maxwell fields, computed using the stress-energy tensor, depends not only on the radiative degrees of fre…
Impact of subdominant modes on the interpretation of gravitational-wave signals from heavy binary black hole systems
Feroz H. Shaik, Jacob Lange, Scott E. Field +5
Over the past year, a handful of new gravitational wave models have been developed to include multiple harmonic modes thereby enabling for the first time fully Bayesian inference s…
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…
Conserved currents for electromagnetic fields in the Kerr spacetime
Alexander M. Grant, Éanna É. Flanagan
We construct a variety of conserved currents for test electromagnetic fields on a Kerr background. Our procedure, which involves the symplectic product for electromagnetism and sym…
Extensions of the asymptotic symmetry algebra of general relativity
Éanna É. Flanagan, Kartik Prabhu, Ibrahim Shehzad
We consider a recently proposed extension of the Bondi-Metzner-Sachs algebra to include arbitrary infinitesimal diffeomorphisms on a (2)-sphere. To realize this extended algebra as…
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…
Model comparison from LIGO-Virgo data on GW170817's binary components and consequences for the merger remnant
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1191
GW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagn…
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…
Symmetries, charges and conservation laws at causal diamonds in general relativity
Venkatesa Chandrasekaran, Kartik Prabhu
We study the covariant phase space of vacuum general relativity at the null boundary of causal diamonds. The past and future components of such a null boundary each have an infinit…

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…
