Abstract: Abstract We consider the effect of grey-body factors on the entanglement island prescription for computing the entropy of an arbitrary subset of the Hawking radiation of an evaporating black hole. When there is a non-trivial… read more here.

Abstract: Quasinormal modes and grey-body factors are spectral characteristics corresponding to different boundary conditions: the former imply purely outgoing waves to the event horizon and infinity, while the latter allow for an incoming wave from the… read more here.

Abstract: Recently, a correspondence between quasinormal modes and grey-body factors of black holes has been established. This correspondence is known to be exact in the eikonal regime for a large class of asymptotically flat black holes… read more here.

DOI: 10.1142/s0217732325501111
Abstract: While gray-body factors for a test scalar field in stringy black holes described by the renowned Gibbons–Maeda–Garfinkle–Horowitz–Strominger (GMGHS) solution have been analyzed in the literature, no such analysis exists for gravitons, likely due to the… read more here.
