Quasinormal modes of string-theoretical black holes
Presenting author: Joćo Carlos Vieira Rodrigues
We analyze the quasinormal modes corresponding to tensorial perturbations of d-dimensional Tangherlini black holes with leading string alpha' corrections. We present simple derivations (based on the WKB approximation) of conditions that determine the asymptotic (highly damped) QNMs for these black holes, obtained by studying the monodromy of the perturbation analytically continued to the complex plane. We explicitly compute these modes in the low-damping limit. Work in collaboration with Filipe Moura.
