"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…
