Accurate initial data for Cauchy-characteristic evolution
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Accurate gravitational-wave (GW) templates from numerical-relativity (NR) simulations are essential for GW science. These templates are typically computed at finite radii and extra…
Calculating gravitational waves at infinity: the missing link
Guido Da Re, Keefe Mitman, Leo C. Stein +7
Gravitational-wave science requires waveform templates to be computed at future null infinity, the asymptotic boundary of spacetime. Numerical solutions of Einstein's equations typ…
NRSur7dq4v2: A multi-domain precessing surrogate model with improved accuracy
Abhishek Ravishankar, Vijay Varma, Scott E. Field +5
Numerical relativity simulations provide the most accurate waveforms for binary black hole coalescences, but are prohibitively expensive for direct use in gravitational-wave data a…
Enabling gravitational-wave astronomy with spin-precessing black holes on generic orbits
Aldo Gamboa, Lorenzo Pompili, Alessandra Buonanno +7
Binary black holes (BBHs) formed in dense stellar environments or in hierarchical triples can coalesce on eccentric orbits and carry spins of arbitrary orientation, leaving distinc…
Accurate waveforms for generic planar-orbit binary black holes: The multipolar effective-one-body model SEOBNRv6EHM
Aldo Gamboa, Alessandra Buonanno, Lorenzo Pompili +8
Accurate and computationally efficient waveform models are required to infer the parameters of compact binaries from their gravitational wave (GW) emission. Among these parameters,…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
Revisiting the Coprecessing Frame in the Presence of Orbital Eccentricity
Lucy M. Thomas, Katerina Chatziioannou, Sam Johar +2
Accurate inclusion of both spin precession and orbital eccentricity effects in gravitational waveform models represents a key hurdle in our ability to fully characterize the proper…
GWTC-4.0: Tests of General Relativity. III. Tests of the Remnants
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1779
This is the third paper of the set recording the results of the suite of tests of general relativity (GR) performed on the signals from the fourth Gravitational-Wave Transient Cata…
GWTC-4.0: Tests of General Relativity. I. Overview and General Tests
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1781
The worldwide LIGO-Virgo-KAGRA network of gravitational-wave (GW) detectors continues to increase in sensitivity, thus increasing the quantity and quality of the detected GW signal…
Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
Fixing the center-of-mass frame of numerical relativity waveforms using the post-Newtonian center-of-mass charge
Aniket Khairnar, Leo C. Stein, Michael Boyle +7
The Bondi--van der Burg--Metzner--Sachs (BMS) frame of gravitational waves produced by numerical relativity (NR) simulations is crucial for building accurate waveform models. A pro…
GWTC-4.0: Tests of General Relativity. II. Parameterized Tests
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
In this second of three papers on tests of general relativity (GR) applied to the compact binary coalescence signals in the 4th Gravitational-Wave Transient Catalog (GWTC-4.0), we…
