Analytic one-loop scattering waveform in general relativity
Year: 2026
Type: article
Abstract: Leveraging the computational framework presented in Brunello and De Angelis [], we evaluate the analytic scattering waveform in general relativity to second order, G 3 M 3 / r b 2 and to all orders in velocity. This new representation of the next-to-leading order waveform is well suited for numerical evaluation. Integrating the (modulus square of the) waveform over the angles on the celestial sphere, we also compute the power spectrum of the radiation to order G 4 numerically.
