Fast neural network surrogate for multimodal effective-one-body gravitational waveforms from generically precessing compact binaries
Christopher Whittall, Geraint Pratten
Gravitational waveform templates are a key ingredient for the detection and characterization of gravitational waves emitted by compact binary mergers in the universe. These templat…

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…

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)…
