Description
In this talk, we will review the extraction of a higher spin gravitational Compton amplitude from low-energy solutions of the Teukolsky equation in the super-extremal (SE) Kerr region (a/Gm ≫ 1), for the scattering of a gravitational wave off the Kerr black hole (BH). We will then use this amplitude to study the non-radiative dynamics for binary systems formed by SE Kerr BHs with their spin oriented in generic directions, up to second order in the post-Minkowskian expansion.
