Long-lived modes and grey-body factors of massive fields in quantum-corrected (Hayward) black holes
Alexey Dubinsky
We study the dynamics of a massive scalar field in the background of the Hayward black hole, which can be interpreted both as a regular spacetime and as an effective geometry arisi…
Scattering and Absorption of Standard Model Fields by Brane-Localized Schwarzschild--de Sitter Black Holes
Alexey Dubinsky
We investigate the propagation and absorption of Standard Model fields -- scalar, electromagnetic, and Dirac -- on a 3+1-dimensional brane embedded in a higher-dimensional Schwarzs…
Gravitational perturbations of Dymnikova black holes: grey-body factors and absorption cross-sections
Alexey Dubinsky
We study axial gravitational perturbations of the Dymnikova regular black hole, an asymptotically flat spacetime in which the Schwarzschild singularity is replaced by a de Sitter c…
Black Holes Immersed in Galactic Dark Matter Halo
Alexey Dubinsky
We analyze the quasinormal modes (QNMs) of scalar, electromagnetic, and Dirac test fields in the background of a black hole immersed in a galactic dark matter halo. The analytic bl…
Long-Lived Quasinormal Modes and Quasi-Resonances around Non-Minimal Einstein-Yang-Mills Black Holes
Alexey Dubinsky
Using accurate computational methods, we compute the quasinormal frequencies of a massive scalar field propagating near a black hole in the framework of non-minimal Einstein-Yang-M…
