Particle motion around magnetized black holes: Preston-Poisson space-time
R. A. Konoplya
We analyze motion of massless and massive particles around black holes immersed in an asymptotically uniform magnetic field and surrounded by some mechanical structure, which provi…
Gravitational spectrum of black holes in the Einstein-Aether theory
R. A. Konoplya, A. Zhidenko
Evolution of gravitational perturbations, both in time and frequency domains, is considered for a spherically symmetric black hole in the non-reduced Einstein-Aether theory. It is…
Magnetized black hole as a gravitational lens
R. A. Konoplya
We use the Ernst-Schwarzschild solution for a black hole immersed in a uniform magnetic field to estimate corrections to the bending angle and time delay due-to presence of weak ma…
Perturbations and quasi-normal modes of black holes in Einstein-Aether theory
R. A. Konoplya, A. Zhidenko
We develop a new method for calculation of quasi-normal modes of black holes, when the effective potential, which governs black hole perturbations, is known only numerically in som…
Stability and quasinormal modes of the massive scalar field around Kerr black holes
R. A. Konoplya, A. Zhidenko
We find quasinormal spectrum of the massive scalar field in the background of the Kerr black holes. We show that all found modes are damped under the quasinormal modes boundary con…
Late time tails of the massive vector field in a black hole background
R. A. Konoplya, C. Molina, A. Zhidenko
We investigate the late-time behavior of the massive vector field in the background of the Schwarzschild and Schwarzschild-de Sitter black holes. For Schwarzschild black hole, at i…
