Network in Neutrinos, Nuclear Astrophysics, and Symmetries (N3AS) Seminar
Explaining nonlinearities in black hole ringdowns from symmetries
Date: Tuesday, January 30th
Time: 2:00 pm
Place: Join Zoom Meeting Meeting ID: 912 3071 4547
Speaker: Antonio Riotto , Geneva U
Abstract: It has been recently pointed out that nonlinear effects are necessary to model the ringdown stage of the gravitational waveform produced by the merger of two black holes giving rise to a remnant Kerr black hole. We show that this nonlinear behavior is explained, both on the qualitative and quantitative level, by near-horizon symmetries of the Kerr black hole within the Kerr/CFT correspondence.
