Description
The central theme of the talk is the direct computation of gravitational waveform produced by the scattering of two black holes through scattering-amplitude methods in the post-Minkowskian expansion. I will discuss how the results of Scattering Amplitude computations match the analytic results from General Relativity in the small-velocity expansion and a novel computational strategy to obtain analytic results to all orders in velocity.
