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…
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…
Gravitational amplitudes in the Regge limit: waveforms, shock waves and unitarity cuts
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +1
Motivated by recent progress in the high-energy description of gravitational scattering, we develop a systematic Regge-theory framework for amplitudes describing the scat…
Analytic structure of the high-energy gravitational amplitude: multi-H diagrams and classical 5PM logarithms
Francesco Alessio, Vittorio Del Duca, Riccardo Gonzo +3
We investigate the high-energy, small-angle limit of two-body gravitational scattering. Using power counting arguments and dispersion relations in an effective field theory for the…
Unexpected Symmetries of Kerr Black Hole Scattering
Dogan Akpinar, Graham R. Brown, Riccardo Gonzo +1
Motivated by the recent introduction of the Dirac bracket framework to compute spinning observables for the scattering of Kerr black holes, we initiate the study of conserved quant…
The spinning self-force EFT: 1SF waveform recursion relation and Compton scattering
Dogan Akpinar, Vittorio del Duca, Riccardo Gonzo
Building on recent approaches, we develop an effective field theory for the interaction of spinning particles modeling Kerr black holes within the gravitational self-force expansio…
The first law of binary black hole scattering
Riccardo Gonzo, Jack Lewis, Adam Pound
In the last decade, the first law of binary black hole mechanics played an important unifying role in the gravitational two-body problem. More recently, binary black hole scatterin…
Gravitational Bound Waveforms from Amplitudes
Tim Adamo, Riccardo Gonzo, Anton Ilderton
With the aim of computing bound waveforms from scattering amplitudes, we explore gravitational two-body dynamics using the Schwinger-Dyson equations and Bethe-Salpeter recursion. W…
Spinning waveforms from KMOC at leading order
Stefano De Angelis, Riccardo Gonzo, Pavel P. Novichkov
We provide the analytic waveform in time domain for the scattering of two Kerr black holes at leading order in the post-Minkowskian expansion and up to fourth order in both spins.…
Wave scattering event shapes at high energies
Riccardo Gonzo, Anton Ilderton
We study the space and properties of global and local observables for radiation emitted in the scattering of a massive scalar field in gauge and gravitational plane-wave background…
Bethe-Salpeter equation for classical gravitational bound states
Tim Adamo, Riccardo Gonzo
The Bethe-Salpeter equation is a non-perturbative, relativistic and covariant description of two-body bound states. We derive the classical Bethe-Salpeter equation for two massive…
Celestial holography on Kerr-Schild backgrounds
Riccardo Gonzo, Tristan McLoughlin, Andrea Puhm
We explore the celestial holography proposal for non-trivial asymptotically flat backgrounds including the Coulomb field of a static and spinning point charge, their gravitational…
Graviton particle statistics and coherent states from classical scattering amplitudes
Ruth Britto, Riccardo Gonzo, Guy R. Jehu
In the two-body scattering problem in general relativity, we study the final graviton particle distribution using a perturbative approach. We compute the mean, the variance and the…
Light-ray operators, detectors and gravitational event shapes
Riccardo Gonzo, Andrzej Pokraka
Light-ray operators naturally arise from integrating Einstein equations at null infinity along the light-cone time. We associate light-ray operators to physical detectors on the ce…
