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…
Gravitational wave forms for extreme mass ratio collisions from supersymmetric gauge theories
Francesco Fucito, Jose Francisco Morales, Rodolfo Russo
We study the wave form emitted by a particle moving along an arbitrary (in general open) geodesic of the Schwarzschild geometry. The mathematical problem can be phrased in terms of…
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…
Post-Newtonian Multipoles from the Next-to-Leading Post-Minkowskian Gravitational Waveform
Alessandro Georgoudis, Carlo Heissenberg, Rodolfo Russo
We consider the frequency-domain LO and NLO post-Minkowskian (PM) waveforms obtained from the tree-level and one-loop amplitudes describing the scattering of two massive scalar obj…
An eikonal-inspired approach to the gravitational scattering waveform
Alessandro Georgoudis, Carlo Heissenberg, Rodolfo Russo
We revisit the amplitude-based derivation of gravitational waveform for the scattering of two scalar black holes at subleading post-Minkowskian (PM) order. We take an eikonal-inspi…
