Title: Tidal and higher curvature effects in gravitational waves from black hole binary binary inspirals in quadratic gravity
Abstract: A major science goal with gravitational waves (GWs) from merging black holes is to probe strong-field gravity in nonlinear, dynamical regimes. This requires accurate predictions of gravitational waveforms in theories beyond General Relativity to understand potential signatures of new gravitational physics, degeneracies with other effects, and gain deeper insights into the information on fundamental gravitational physics contained in various GW parameters. This talk will focus on an example of quadratic gravity theories where black holes develop scalar hair. I will discuss the effects of higher-curvature nonlinearities and tidal interactions on the GW signals from binary inspirals and consequences of including self-interactions of the scalar field in the theory. I will conclude with an outlook to future prospects and remaining challenges, as larger and more precise gravitational-wave dataset will become available and their science exploitation will start to be limited by the theoretical modeling.
