Abstract

In recent years, gravitational wave observations of compact objects have provided new opportunities to test our understanding of gravity in the strong-field, highly dynamical regime.

To perform model-dependent tests of General Relativity with these observations, as well as to guide theory-agnostic tests, it is crucial to develop accurate inspiral-merger-ringdown waveforms in alternative theories of gravity.

In this talk, we discuss the challenges, recent progress, and future directions in incorporating modifications to full General Relativity. As a concrete example, we consider Einstein-scalar-Gauss-Bonnet gravity, which introduces deviations from General Relativity at small curvature length scales.
