Description
The analysis of gravitational-wave events requires fast and accurate theoretical predictions. I focus on Effective-One-Body (EOB) models informed by Post-Minkowskian (PM) results and Numerical Relativity (NR) simulations. I compare analytical and numerical results for binary scatterings, including spin and tidal effects. Finally, I discuss the use of PM results for bound systems by means of a Lagrangian formalism.
