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 …

The WKB approach for finding quasinormal modes of black holes, suggested in Schutz and
Will (1985 Astrophys. J. Lett. 291 L33–6) by Schutz and Will at the first order and later …

The Bardeen black hole holds historical significance as the first model of a regular black
hole. Recently, there have been proposed interpretations of the Bardeen spacetime as …

Massive bosonic fields of arbitrary spin are predicted by general extensions of the standard
model. It has been recently shown that there exists a family of bimetric theories of gravity …

In this work we consider a generalized Bronnikov-Ellis wormhole and the tideless Morris-
Thorne wormhole and we study the propagation of massive scalar fields. We calculate the …

The spherically symmetric deformation of the Schwarzschild solution owing to the quantum
corrections to gravity is known as Kazakov-Solodukhin black-hole metric. Neglecting non …

Classical (quasinormal) and quantum (Hawking) radiations are investigated for test fields in
the background of a four dimensional, spherically symmetric and asymptotically flat black …

The Newman-Janis algorithm, which involves complex-coordinate transformations,
establishes connections between static and spherically symmetric black holes and rotating …

Recently it has been argued that the phantom thin-shell wormholes matched with the
Schwarzschild space-time near the Schwarzschild radius ring like Schwarzschild black …
