KITP conference "Nonlinearities in Strong Gravity: Perturbation Theory, Amplitudes, and Numerics"

The KITP conference "Nonlinearities in Strong Gravity: Perturbation Theory, Amplitudes, and Numerics" will run May 30, 2028 – Jun 2, 2028. The strong-field spacetime near a compact-object binary is rich with information about gravitational interactions, yet capturing it faithfully remains a formidable challenge for theoretical models. This conference addresses that challenge by focusing on the critical interfaces between four approaches: matching weak-field analytical results to the strong-field regime, modelling nonlinearities across the inspiral, merger, and ringdown phases, and connecting theoretical waveform predictions to observational data analysis. It will bring together experts in bl
