Perturbations of black holes, initially considered in the context of possible observations of
astrophysical effects, have been studied for the past 10 years in string theory, brane-world …

We present a comprehensive black-hole event generator, BlackMax, which simulates the
experimental signatures of microscopic and Planckian black-hole production and evolution …

In this paper, we thoroughly explore two crucial aspects of a quantum Schwarzschild black
solution within four-dimensional space–time:(i) the weak deflection angle,(ii) the rigorous …

We make an extensive study of evolution of gravitational perturbations of D-dimensional
black holes in Gauss-Bonnet theory. There is an instability at higher multipoles ℓ and large …

We study the greybody factors, quasinormal modes, and shadow of the higher dimensional
de-Sitter (dS)/anti de-Sitter (AdS) black hole spacetimes derived from the Einstein …

Using the WKB approximation, massless and massive Dirac quasinormal modes (QNMs)
are studied<? format?> in spherically symmetric regular spacetimes. We analyze the …

A bstract In this article, we extend our study on a new class of modular Hamiltonians on an
interval attached to the origin on the semi-infinite line, introduced in a recent work dedicated …

Quasinormal modes of a massive Dirac field were calculated for various static black hole
backgrounds with the help of the WKB formula. These estimations, however, are rough and …

In this work, we probe the stability of az= 3 three-dimensional Lifshitz black hole by using
scalar and spinorial perturbations. We found an analytical expression for the quasinormal …
