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 …

Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

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

The decay behavior of a massless scalar field in the Schwarzschild-de Sitter spacetime is
well-known to follow an exponential law at asymptotically late times t→∞. In contrast, a …

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 the …

In this paper, we discuss hidden symmetries in rotating black hole spacetimes. We start with
an extended introduction which mainly summarizes results on hidden symmetries in four …

We compute the spectrum of quasinormal frequencies of five-dimensional black holes
obtained in noncommutative geometry. In particular, we study scalar perturbations of a …

We compute the quasinormal modes of massive scalar and Dirac fields within the framework
of asymptotically de Sitter black holes in Euler–Heisenberg non-linear electrodynamics. We …

Recently, the anomalous decay rate of quasinormal modes has been studied for some
geometries under scalar field perturbations, which occurs when the longest-lived modes are …

Abstract Bardeen de-Sitter (BdS) black hole is a spherically symmetric solution of Einstein's
equation which is coupled to nonlinear electromagnetic field in a way that one gets a regular …
