Grey-body factor from correspondence with quasinormal mode for gravitational perturbation of higher-dimensional Reissner-Nordström black hole
Hyewon Han, Bogeun Gwak
We investigate the correspondence between quasinormal modes (QNMs) and grey-body factors (GBFs) of higher-dimensional Reissner-Nordström black holes. Considering gravitational pert…
Phase Transitions with Lyapunov Exponents under Einstein and String Frames in Dilatonic Reissner--Nordström--AdS Black Holes
Hocheol Lee, Bogeun Gwak
We investigate Lyapunov exponents as dynamical probes of black hole phase transitions in dilatonic Reissner--Nordström--AdS black holes within Einstein--Maxwell--dilaton theory. Th…
Correspondence between quasinormal modes and grey-body factors of Schwarzschild--Tangherlini black holes
Hyewon Han, Bogeun Gwak
We investigate the correspondence between the quasinormal modes and grey-body factors of Schwarzschild--Tangherlini black holes. The gravitational perturbations in higher-dimension…
Unbounded Radius of Innermost Stable Circular Orbit in Higher-Dimensional Black Holes
Hocheol Lee, Bogeun Gwak
The innermost stable circular orbit (ISCO) offers a fundamental test of spacetime structure. However, its behavior in higher-dimensional black holes influenced by anisotropic energ…
Frame Dependence of Bound on Lyapunov Exponent in Dilatonic Reissner-Nordström-AdS and Kerr-Sen-AdS Black Holes
Hocheol Lee, Bogeun Gwak
We investigate the frame dependence of the Lyapunov exponent bound for charged particles in dilatonic Reissner-Nordström-AdS and Kerr-Sen-AdS black hole backgrounds, derived from E…
Correspondence between quasinormal modes and grey-body factors in five-dimensional black holes
Hyewon Han, Bogeun Gwak
We investigate the correspondence between quasinormal modes and grey-body factors for the five-dimensional Schwarzschild--Tangherlini black hole. The quasinormal modes of gravitati…
