Charged black hole surrounded by a galactic halo in de Sitter universe
R. A. Konoplya, Z. Stuchlík, A. Zhidenko
Assuming a sufficiently general form for the matter distribution function of a galactic halo, we have derived solutions to the Einstein-Maxwell equations describing a charged black…

Nonoscillatory gravitational quasinormal modes of Reissner-Nordström-de Sitter spacetime
Z. Stuchlík, A. Zhidenko
We revisit quasinormal modes of Reissner-Nordström-de Sitter black holes, a classical and seemingly well-understood solution of Einstein-Maxwell theory with a positive cosmological…

Overtones behavior of higher dimensional black holes in the Einstein-Gauss-Bonnet gravity
Z. Stuchlík, A. Zhidenko
Gravitational perturbations of higher-dimensional black holes in the Einstein-Gauss-Bonnet theory, proposed by Boulware and Deser, have been extensively studied in numerous works,…
