Inspiral-merger-ringdown waveforms with gravitational self-force results within the effective-one-body formalism
Benjamin Leather, Alessandra Buonanno, Maarten van de Meent
Gravitational self-force (GSF) theory is a strong-gravity perturbative approach to the relativistic two-body problem, primarily developed to model extreme-mass-ratio inspirals, whe…

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…

Gravitational self-force with hyperboloidal slicing and spectral methods
Benjamin Leather
We present a novel approach for calculating the gravitational self-force (GSF) in the Lorenz gauge, employing hyperboloidal slicing and spectral methods. Our method builds on the p…
