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 review black-hole solutions of higher-dimensional vacuum gravity and higher-
dimensional supergravity theories. The discussion of vacuum gravity is pedagogical, with …

Geodesic motion determines important features of spacetimes. Null unstable geodesics are
closely related to the appearance of compact objects to external observers and have been …

The orbital and oscillatory motion of test particles around a non-rotating, conformally
coupled charged black hole with scalar hair is studied in this work. The impact of the black …

We study characteristic (quasinormal) modes of a D-dimensional Schwarzschild black hole.
It is shown that the real parts of the complex quasinormal modes, representing the real …

We investigate the instability of the massive scalar field in the vicinity of a rotating black hole.
The instability arises from amplification caused by the classical superradiance effect. The …

This book is about black holes, one of the most intriguing objects of modern theoretical
physics and astrophysics. For many years, black holes have been considered as interesting …

The shadow of a rotating non-Kerr black hole has been studied, and it was shown that in
addition to the specific angular momentum a, the deformation parameter of non-Kerr …

We investigate the shadow cast by a rotating braneworld black hole, in the Randall-
Sundrum scenario. In addition to the angular momentum, the tidal charge term deforms the …

We start by reviewing the existing literature on the creation of black holes during high-
energy particle collisions, both in the absence and in the presence of extra, compact …
