Wave and particle probes of a regular T-duality-inspired black hole with gravitational self-energy
Alexey Dubinsky
Recently it was shown that a non-local T-duality-inspired smearing of the point mass introduces a finite zero-point length, while the regularized Newtonian gravitational self-energ…
From Ringdown to Lensing: Analytic Eikonal Modes of Quasi-Topological Regular Black Holes
Alexey Dubinsky
We develop an analytic eikonal description of perturbations for four-dimensional regular black holes in quasi-topological gravity. Using first-order Schutz--Will WKB together with…
Scattering of a scalar field in the four-dimensional quasi-topological gravity
Alexey Dubinsky
We study grey-body factors for a massless scalar field in the spacetime of regular black holes arising in four-dimensional non-polynomial quasi-topological gravity. We consider two…
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…

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…

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…
Grey-body factors for gravitational and electromagnetic perturbations around Gibbons-Maeda-Garfinkle-Horovits-Strominger black holes
Alexey Dubinsky
While grey-body factors for a test scalar field in stringy black holes described by the renowned Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) solution have been analyzed in…
Analytic expressions for grey-body factors of the general parametrized spherically symmetric black holes
Alexey Dubinsky, Antonina F. Zinhailo
In light of the recently discovered connection between grey-body factors and quasinormal ringing, we derive analytic expressions for the grey-body factors of generic parametrized s…
Analytic expressions for quasinormal modes of the general parametrized spherically symmetric black holes and the Hod's proposal
Alexey Dubinsky
Using an expansion in terms of the inverse multipole number and the WKB approach, we derive an analytic expression for generic parametrized spherically symmetric and asymptotically…
Quasinormal modes of charged black holes in Asymptotically Safe Gravity
Alexey Dubinsky
We calculate quasinormal modes of scalar and neutrino perturbations around the charged black hole in Asymptotically Safe Gravity. We show that the charge and coupling constant chan…
Quantum gravitational corrections to the Schwarzschild spacetime and quasinormal frequencies
Alexey Dubinsky
Quantum gravitational corrections to the entropy of the Schwarzschild black hole, derived using the Wald entropy formula within an effective field theory framework, were presented…
Overtones of black holes via time-domain integration
Alexey Dubinsky
We show that first several overtones could calculated by the time-domain integration method for asymptotically de Sitter black holes already at the lowest multipole numbers of grav…
Asymptotic decay and quasinormal frequencies of scalar and Dirac fields around dilaton-de Sitter black holes

Alexey Dubinsky
We examine perturbations of a massive scalar field around spherically symmetric, brane-localized black holes. Although the ringdown and asymptotic tails of various brane-world blac…
