Quasinormal modes as exterior probes of black hole interiors in our Universe
Sašo Grozdanov, Vita Movrin, Samuel Valach
We consider a scenario in which a black hole is enclosed in a reflecting timelike cavity and linearly perturbed. For the resulting quasinormal spectra of gravitational, electromagn…

Bouncing Geodesics, Singularities, and the Cavity Thermal Product Formula in Asymptotically Flat and de Sitter Black Holes
Sašo Grozdanov, Vita Movrin, Samuel Valach
We investigate the existence and implications of ``bouncing geodesics'' in asymptotically flat Schwarzschild and Schwarzschild--de Sitter black holes. These trajectories, which pro…

Bouncing geodesics, black hole singularities, and singularities of thermal correlators
Sašo Grozdanov, Samuel Valach, Mile Vrbica
Bouncing geodesics have been used as valuable probes of black hole singularities. In the dual boundary theory, the presence of bouncing geodesics is encoded in the analytic structu…
