Time-domain framework for the Teukolsky equation with a particle source using comoving hyperboloidal coordinates
Aditya Vaswani, Leor Barack, Oliver Long +1
We present a scheme and implementation code for time-domain integration of the Teukolsky equation in 1+1 dimensions with a point-particle source, based on comoving, spatially compa…
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,…
Resummed energy loss in extreme-mass-ratio scattering using critical orbits
Leor Barack, Riccardo Gonzo, Benjamin Leather +2
Motivated by recent efforts to bridge between weak-field and strong-field descriptions of black-hole binary dynamics, we develop a resummation scheme for post-Minkowskian radiative…
Black-hole scattering with numerical relativity: Self-force extraction and post-Minkowskian validation
Oliver Long, Harald P. Pfeiffer, Lawrence E. Kidder +1
The asymptotic nature of unbound binary-black-hole encounters provides a clean method for comparing different approaches for modeling the two-body problem in general relativity. In…
Parameter control for binary black hole initial data
Iago B. Mendes, Nils L. Vu, Oliver Long +2
When numerically solving Einstein's equations for binary black holes (BBH), we must find initial data on a three-dimensional spatial slice by solving constraint equations. The cons…
Frequency-domain self-force calculations using Gegenbauer reconstruction
Christopher Whittall, Leor Barack, Oliver Long
We investigate the use of the Gegenbauer procedure for time-domain reconstruction in frequency-domain calculations of the self-force on a particle orbiting a black hole. The conven…
Highly accurate simulations of asymmetric black-hole scattering and cross validation of effective-one-body models
Oliver Long, Harald P. Pfeiffer, Alessandra Buonanno +6
The study of unbound binary-black-hole encounters provides a gauge-invariant approach to exploring strong-field gravitational interactions in two-body systems, which can subsequent…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Black hole scattering near the transition to plunge: Self-force and resummation of post-Minkowskian theory
Oliver Long, Christopher Whittall, Leor Barack
Geodesic scattering of a test particle off a Schwarzschild black hole can be parameterized by the speed-at-infinity and the impact parameter , with a "separatrix", $b=b_c(v)…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
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…
