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…
