Intermediate Asymptotics of the Kerr Quasinormal Spectrum
Shahar Hod, Uri Keshet
Abstract
We study analytically the quasinormal mode spectrum of near-extremal (rotating) Kerr black holes. We find an analytic expression for these black-hole resonances in terms of the black-hole physical parameters: its Bekenstein-Hawking temperature TBH and its horizon's angular velocity Ω, which is valid in the intermediate asymptotic regime 1<<ω<<1/TBH.
