Fully nonlinear transformations of the Weyl-Bondi-Metzner-Sachs asymptotic symmetry group

Eanna E. Flanagan, David A. Nichols

The asymptotic symmetry group of general relativity in asymptotically flat spacetimes can be extended from the Bondi-Metzner-Sachs (BMS) group to the generalized BMS (GMBS) group s…

How to Detect an Astrophysical Nanohertz Gravitational-Wave Background

Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93

Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…

Fully relativistic three-dimensional Cauchy-characteristic matching for physical degrees of freedom

Sizheng Ma, Jordan Moxon, Mark A. Scheel +8

A fully relativistic three-dimensional Cauchy-characteristic matching (CCM) algorithm is implemented for physical degrees of freedom in a numerical relativity code SpECTRE. The met…

Extending black-hole remnant surrogate models to extreme mass ratios

Matteo Boschini, Davide Gerosa, Vijay Varma +19

Numerical-relativity surrogate models for both black-hole merger waveforms and remnants have emerged as important tools in gravitational-wave astronomy. While producing very accura…

Numerical relativity surrogate model with memory effects and post-Newtonian hybridization

Jooheon Yoo, Keefe Mitman, Vijay Varma +12

Numerical relativity simulations provide the most precise templates for the gravitational waves produced by binary black hole mergers. However, many of these simulations use an inc…

Numerical simulations of black hole-neutron star mergers in scalar-tensor gravity

Sizheng Ma, Vijay Varma, Leo C. Stein +5

We present a numerical-relativity simulation of a black hole - neutron star merger in scalar-tensor (ST) gravity with binary parameters consistent with the gravitational wave event…

Worldtube excision method for intermediate-mass-ratio inspirals: scalar-field model in 3+1 dimensions

Nikolas A. Wittek, Mekhi Dhesi, Leor Barack +10

Binary black hole simulations become increasingly more computationally expensive with smaller mass ratios, partly because of the longer evolution time, and partly because the lengt…

Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array

M. Falxa, S. Babak, P. T. Baker +123

The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…

Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes

Lorenzo Pompili, Alessandra Buonanno, Héctor Estellés +21

We present SEOBNRv5HM, a more accurate and faster inspiral-merger-ringdown gravitational waveform model for quasi-circular, spinning, nonprecessing binary black holes within the ef…

Open data from the third observing run of LIGO, Virgo, KAGRA and GEO

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1741

The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data…

Motion of a spinning particle under the conservative piece of the self-force is Hamiltonian to first order in mass and spin

Francisco M. Blanco, Éanna É. Flanagan

We consider the motion of a point particle with spin in a stationary spacetime. We define, following Witzany (2019) and later Ramond (2022), a twelve dimensional Hamiltonian dynami…
