From amplitudes to gravitational radiation with cubic interactions and tidal effects

no code implementations11 Dec 2020 Manuel Accettulli Huber, Andreas Brandhuber, Stefano De Angelis, Gabriele Travaglini

Working in an effective field theory set-up, we compute the modifications to the quadrupole moment due to $I_1$, $G_3$ and tidal interactions, from which we obtain the power of gravitational waves radiated in the process to first order in the perturbations and leading order in the post-Minkowskian expansion.

Eikonal phase matrix, deflection angle and time delay in effective field theories of gravity

no code implementations3 Jun 2020 Manuel Accettulli Huber, Andreas Brandhuber, Stefano De Angelis, Gabriele Travaglini

From the eigenvalues of the eikonal phase matrix we then extract two physical observables, to 2PM order: the classical deflection angle and Shapiro time delay/advance.
