DOI: 10.1103/physrevd.100.103013
Abstract: Motivated by black holes surrounded by accretion structures, we consider in this series static and axially symmetric black holes "perturbed" gravitationally as being encircled by a thin disc or a ring. In previous papers, we… read more here.

DOI: 10.1139/cjp-2016-0900
Abstract: In this paper, we study the geodesic motion around a regular magnetic black hole in non-minimal Einstein–Yang–Mills theory with cosmological constant. For this purpose, we derive the equations of motion for massive and photon-like particles.… read more here.
