[astroseminar at Sapienza] Gravity theory webinar Wed May 5th @4pm: Justin Ripley (DAMTP, Cambridge University) - "Computing the second order curvature perturbations of Kerr black holes"

[Paolo Pani]

Announcement of the next gravity-theory webinar:

*Justin Ripley (DAMTP, Cambridge University)  - "Computing the second order
curvature perturbations of Kerr black holes"*
*Wed, May 5th @4pm*

Abstract:
*I will describe a formalism to compute the second order gravitational
(vacuum) perturbations of Kerr black holes, a numerical code that
implements that formalism, and example output from the code. To motivate
this work, I will discuss several applications where going beyond linear
perturbation theory may be necessary, including modeling the “ringdown” of
(near extremal) Kerr black holes, modeling “black hole turbulence”, and the
self-force problem. I will discuss what our current results have to say on
those issues, and directions for future work.*
