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…
Asymptotic decay and quasinormal frequencies of scalar and Dirac fields around dilaton-de Sitter black holes
Alexey Dubinsky, Antonina Zinhailo
We study the decay of Dirac and massive scalar fields at asymptotically late times in the background of the charged asymptotically de Sitter dilatonic black holes. It is shown that…
Exploring Unique Quasinormal Modes of a Massive Scalar Field in Brane-World Scenarios
Antonina F. Zinhailo
We compute precise values of quasinormal modes of a massive scalar field in the background of the Schwarzschild-like brane-localised black holes. It is shown that the quasinormal s…
Quasinormal spectrum in the asymptotically safe gravity
A. F. Zinhailo
Asymptotically safe gravity is based on the idea of the dependence of the gravitational coupling upon the distance from the origin, approaching its classical value in the weak fiel…
Quasinormal modes of renormalization group improved Dymnikova regular black holes
R. A. Konoplya, Z. Stuchlik, A. Zhidenko +1
We find accurate quasinormal frequencies of a quantum corrected black hole constructed in the renormalization group theory via the coordinate-independent iterative procedure, leadi…
Quasinormal modes and Hawking radiation of black holes in cubic gravity
R. A. Konoplya, A. F. Zinhailo, Z. Stuchlik
We consider quasinormal modes and Hawking radiation of four-dimensional asymptotically flat black holes in the most general up to-cubic-order-in-curvature dimension-independent Ein…
Grey-body factors and Hawking radiation of black holes in Einstein-Gauss-Bonnet gravity
Roman A. Konoplya, Antonina F. Zinhailo
The -dimensional Einstein-Gauss-Bonnet theory of gravity which breaks the Lorentz invariance in a theoretically consistent and observationally viable way has been recently s…
Quasinormal modes, stability and shadows of a black hole in the 4D Einstein-Gauss-Bonnet gravity
R. A. Konoplya, A. F. Zinhailo
Recently a -dimensional regularization approach leading to the non-trivial -dimensional Einstein-Gauss-Bonnet (EGB) effective description of gravity was formulated which…
Quasinormal modes of Dirac field in the Einstein-dilaton-Gauss-Bonnet and Einstein-Weyl gravities
A. F. Zinhailo
Quasinormal modes of Dirac field in the background of a non-Schwarzschild black holes in theories with higher curvature corrections are investigated in this paper. With the help of…
Higher order WKB formula for quasinormal modes and grey-body factors: recipes for quick and accurate calculations
R. A. Konoplya, A. Zhidenko, A. F. Zinhailo
The WKB approach for finding quasinormal modes of black holes, suggested in [1] by Schutz and Will at the first order and later developed to higher orders [2-4], became popular dur…
Quasinormal modes, scattering and Hawking radiation in the vicinity of Einstein-dilaton-Gauss-Bonnet black hole
R. A. Konoplya, A. F. Zinhailo, Z. Stuchlík
Classical (quasinormal) and quantum (Hawking) radiations are investigated for test fields in the background of a four dimensional, spherically symmetric and asymptotically flat bla…
Quasinormal modes of the four-dimensional black hole in Einstein-Weyl gravity
A. F. Zinhailo
In this paper we consider quasi-normal modes of test scalar and electromagnetic fields in the background of a non-Schwarzschild black hole in the Einstein-Weyl gravity. We find the…
