Title: Quasinormal modes for Kerr-AdS spacetimes
Speaker: Oran Gannot
Speaker Info: Berkeley
Brief Description:
Special Note:

Kerr-AdS spacetimes are rotating black hole solutions to the Einstein equations with negative cosmological constant. Recently, time-periodic approximate solutions (quasimodes) for the Klein-Gordon equation were constructed on these spacetimes by Holzegel-Smulevici as a way of proving lower bounds on uniform energy decay. I will show how these quasimodes can be used to exhibit sequences of quasinormal modes (outgoing waves) at complex frequencies which converge exponentially to the real axis.
