PGI Seminar Series Spring 2023|Lam Hui|Columbia University|Black hole perturbation theory: Love numbers and nonlinear ring-down

Mar 27, 2023, 12:30 pm1:30 pm


Event Description

We will discuss two recent developments in black hole perturbation theory: 
(1) the symmetries behind the well-known vanishing of the tidal Love numbers, and
(2) second order quasi-normal modes during the ring-down phase after a binary merger.
