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…
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…
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…
Revisiting gravitational angular momentum and mass dipole losses in the eikonal framework
Carlo Heissenberg, Rodolfo Russo
We review the description of classical gravitational scatterings of two compact objects by means of the eikonal framework. This encodes via scattering amplitudes both the motion of…
