Learning more from Kerr - New tools and related results

Feb. 23 - 14:30 - 2023

Speaker: Lionel London (King's College London)

Title: Learning more from Kerr - New tools and related results


There is good reason to think that gravitational wave physics, and particularly single black hole perturbation theory, is at a turning point. In this talk, I will review some of the challenges currently facing our understanding of single perturbed black holes. The setting of this review will be gravitational waves from the merger of stellar mass binary black holes (BBHs), and related conceptual tensions. I will pay particular attention to the relevance of Kerr “quasi-normal modes” (QNMs) to BBH merger, and I will discuss how our burgeoning understanding of QNM orthogonality points the way to new directions of research. As an example, I will present a proof-of-concept for a purely spectral method of solving Teukoslky’s radial equation.
