Point particles in general relativity: beyond linear perturbation theory
Jørgen Musaeus, Adam Pound, Samuel D. Upton
Point particles are generically ill defined in fully nonlinear general relativity, although they are naturally well defined in linear perturbation theory. In a previous paper, two…
Second-order Teukolsky calculations for nonspinning, quasicircular binaries
Benjamin Leather, Andrew Spiers, Adam Pound +4
Currently, the only second-order gravitational self-force calculations have been based on directly solving the perturbative Einstein equations in the Lorenz gauge. That method reli…
Dissection of a merger-ringdown waveform in the small-mass-ratio limit
Patrick Bourg, Lorenzo Küchler, Benjamin Leather +6
Work over the past two decades has unveiled the rich phenomenology of black hole binary mergers and subsequent ringdowns, involving a tapestry of quasinormal modes (QNMs), nonlinea…
Black hole mergers beyond general relativity: a self-force approach
Ayush Roy, Lorenzo Küchler, Adam Pound +1
Gravitational waves from binary black hole mergers provide a glimpse of gravitational dynamics in its most extreme observable regime, potentially enabling precision tests of genera…
Quadratic quasinormal modes at null infinity on a Schwarzschild spacetime
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
The ringdown of perturbed black holes has been studied since the 1970s, but until recently, studies have focused on linear perturbations. There is now burgeoning interest in nonlin…
Quadratic quasi-normal mode dependence on linear mode parity
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
Quasinormal modes (QNMs) uniquely describe the dominant piece of the gravitational-wave ringdown of postmerger black holes. While the linear QNM regime has been extensively studied…
Multi-domain spectral method for self-force calculations
Rodrigo Panosso Macedo, Patrick Bourg, Adam Pound +1
Second-order self-force calculations will be critical for modelling extreme-mass-ratio inspirals, and they are now known to have high accuracy even for binaries with mass ratios $\…
Simple, efficient method of calculating the Detweiler-Whiting singular field to very high order
Patrick Bourg, Adam Pound, Samuel D. Upton +1
Most self-force calculations rely, in one way or another, on representations of a particle's Detweiler- Whiting singular field. We present a simple method of calculating the singul…
Worldtube excision method for intermediate-mass-ratio inspirals: self-consistent evolution in a scalar-charge model
Nikolas A. Wittek, Adam Pound, Harald P. Pfeiffer +1
This is a third installment in a program to develop a method for alleviating the scale disparity in binary black hole simulations with mass ratios in the intermediate astrophysical…
Implementation of a GHZ-Teukolsky puncture scheme for gravitational self-force calculations
Patrick Bourg, Benjamin Leather, Marc Casals +2
Post-adiabatic models of extreme- and intermediate-mass-ratio inspirals will require calculations of second-order gravitational self-force effects in the spacetime of a spinning, K…
Spin-2 Green's Functions on Kerr in Radiation Gauge
Marc Casals, Stefan Hollands, Adam Pound +1
We construct retarded and advanced Green's functions for gravitational perturbations in Kerr in an ingoing radiation gauge. Our Green's functions have a frequency domain piece that…
