Angular Momentum Loss at Fourth Post-Minkowskian Order
Alessandro Georgoudis, Carlo Heissenberg, Gustav Mogull +1
We calculate the total loss of angular momentum for a gravitational scattering of two non-spinning point-like objects at . Our methodology combines use of both am…
"Waveforms" at the Horizon
Andrea Cipriani, Francesco Fucito, Carlo Heissenberg +2
We study perturbations induced by a light particle scattering off a Schwarzschild black hole. Exploiting recent results for the wave propagation in this geometry, we derive the fie…
Reconstructing the Gravitational Waveform from Its Probe Limit
Carlo Heissenberg, Rodolfo Russo
Gravitational observables for binary systems exhibit a simple polynomial dependence on the masses , of the two scattering objects when they are written in terms of the a…
Finite actions and asymptotic charges at null infinity for any spin
Andrea Campoleoni, Arnaud Delfante, Dario Francia +1
We identify boundary terms renormalizing the free on-shell actions for massless fields of arbitrary spin, including electromagnetism and linearized gravity, with boundary condition…
Nonlinear Gravitational Memory in the Post-Minkowskian Expansion
Alessandro Georgoudis, Vasco Goncalves, Carlo Heissenberg +1
We present the first computation of the nonlinear gravitational memory waveform for the scattering of two compact objects in General Relativity at leading order in the post-Minkows…
Radiation-Reaction and Angular Momentum Loss at
Carlo Heissenberg
We point out that the odd-in-velocity contribution to the radiated angular momentum for two-body scattering is determined by the radiation-reaction (RR) term in…
