The missing asymptotic sector of rotating black-hole spectroscopy
Uri Keshet, Arnon Ben-Meir
The rotation of a black hole splits its spectrum in two, yet only one sector is known in the highly-damped regime. We find the second, at least partly oblate sector, with quasinorm…

Analytic Study of Rotating Black-Hole Quasinormal Modes
Uri Keshet, Shahar Hod
A Bohr-Sommerfeld equation is derived for the highly-damped quasinormal mode frequencies omega(n>>1) of rotating black holes. It may be written as 2\int_C(p_r+ip_0)dr=(n+1/2)h, whe…

Intermediate Asymptotics of the Kerr Quasinormal Spectrum
Shahar Hod, Uri Keshet
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 bla…
