Towards ultrarelativistic scattering near the light ring: asymptotic divergence of gravitational-wave fluxes
David Trestini, Riccardo Gonzo, Benjamin Leather
Near the threshold between scattering and capture by a Schwarzschild black hole, a particle spends a long time close to an unstable circular orbit, which in the ultrarelativistic l…
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…
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…
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…
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…
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…
Worldtube puncture scheme for first- and second-order self-force calculations in the Fourier domain
Jeremy Miller, Benjamin Leather, Adam Pound +1
Second-order gravitational self-force theory has recently led to the breakthrough calculation of ``first post-adiabatic'' (1PA) compact-binary waveforms [Phys. Rev. Lett. 130, 2414…
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…
Applying the effective-source approach to frequency-domain self-force calculations for eccentric orbits
Benjamin Leather, Niels Warburton
Extreme mass-ratio inspirals (EMRIs) are expected to have considerable eccentricity when emitting gravitational waves (GWs) in the LISA band. Developing GW templates that remain ph…
Hyperboloidal method for frequency-domain self-force calculations
Rodrigo Panosso Macedo, Benjamin Leather, Niels Warburton +2
Gravitational self-force theory is the leading approach for modeling gravitational wave emission from small mass-ratio compact binaries. This method perturbatively expands the metr…
