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…
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…
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…
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…
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…
