# Black hole perturbation theory and gravitational self-force

@inproceedings{Pound2021BlackHP, title={Black hole perturbation theory and gravitational self-force}, author={Adam Pound and Barry Wardell}, year={2021} }

Much of the success of gravitational-wave astronomy rests on perturbation theory. Historically, perturbative analysis of gravitational-wave sources has largely focused on post-Newtonian theory. However, strong-field perturbation theory is essential in many cases such as the quasinormal ringdown following the merger of a binary system, tidally perturbed compact objects, and extreme-mass-ratio inspirals. In this review, motivated primarily by small-mass-ratio binaries but not limited to them, we…
