Gravitational Wave Precision Observables and Waveforms from Scattering Amplitudes

In recent years, Scattering Amplitudes methods, developed for computations in relativistic Quantum Field Theories, have been applied to compute observables which are relevant for the generation of Gravitational Wave templates. In the first part of the talk, I will give a review of recent achievements. In the second part of the talk, I will talk about new attempts to compute gravitational waveforms directly from Amplitudes, their matching to classical results from General Relativity and ongoing developments.
