Asymptotic quasinormal mode spectrum of rotating black holes

Abstract

Motivated by novel results in the theory of black-hole quantization, we study {\it analytically} the quasinormal modes (QNM) of ({\it rotating}) Kerr black holes. The black-hole oscillation frequencies tend to the asymptotic value ${\omega }_n=m\Omega +i2\pi T_{BH}n$ in the $n\to \infty$ limit. This simple formula is in agreement with Bohr's correspondence principle. Possible implications of this result to the area spectrum of quantum black holes are discussed.
