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…
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…
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…
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…
