Asymptotic quasinormal modes of string-theoretical d-dimensional black holes

Journal of High Energy Physics, 2021
We compute the quasinormal frequencies of d-dimensional spherically symmetric black holes with leading string α′ corrections for tensorial gravitational perturbations in the highly damped regime.

Bound states of spinning black holes in five dimensions [PDF]

, 2017
We find and study supergravity BPS bound states of five-dimensional spinning black holes in asymptotically flat spacetime. These solutions follow from multi-string solutions in six-dimensional minimal supergravity and can be uplifted to F-theory or M ...

Exact Three Dimensional Black Holes in String Theory [PDF]

, 1993
A black hole solution to three dimensional general relativity with a negative cosmological constant has recently been found. We show that a slight modification of this solution yields an exact solution to string theory.

Extremal black hole horizons

Journal of High Energy Physics, 2018
Using the blackfold effective theory applied to extremal Kerr branes we provide evidence for the existence of new stationary extremal black hole solutions in asymptotically flat spacetime with both single and multiple disconnected horizons. These include

Short distance space-time structure and black holes in string theory: A Short review of the present status [PDF]

, 1998
We briefly review the present status of string theory from the viewpoint of its implications on the short-distance space-time structure and black hole physics.

Non-supersymmetric F1-P black rings

Journal of High Energy Physics
We construct singly and doubly spinning non-supersymmetric F1–P black ring solutions in five-dimensional supergravity. These black rings have regular horizons and non-zero temperature.

Geroch group description of bubbling geometries

Journal of High Energy Physics, 2018
The Riemann-Hilbert approach to studying solutions of supergravity theories allows us to associate spacetime independent monodromy matrices (matrices in the Geroch group) with solutions that effectively only depend on two spacetime coordinates.
