A way to test electromagnetic field and spacetime properties around black holes is by
considering the dynamics of test particles. In fact, in real astrophysical scenarios, it is hard to …

In the present work, we aimed to investigate the dynamics of spinning charged and
magnetized test particles around both electrically and magnetically charged quantum …

We study the dynamics of charged test particles around an electrically charged black hole in
Einstein–Maxwell-scalar (EMS) gravity. The event horizon properties of the spacetime …

General relativity (GR) is a well-tested theory of gravity in strong and weak field regimes.
Many modifications to this theory were obtained, including different scalar, vector, and tensor …

General relativity (GR) theory modifications include different scalar, vector, and tensor fields
with non-minimal gravitational coupling. Kalb–Ramond (KR) gravity is a modified theory …

The study of electromagnetic interactions among test particles with electric charges and
magnetic dipole moments is of great significance when examining the dynamics of particles …

Throughout this work, we explored the dynamics of test particles with magnetic dipole
moment around magnetized rotating Kerr black holes in scalar–vector–tensor gravity theory …

We study the circular motion of particles with magnetic dipole moment around
Schwarzschild black holes immersed in external asymptotically uniform and dipolar …

One of the most important issues in relativistic astrophysics is to explain the origin
mechanisms of (ultra) high energy charged particle components of cosmic rays. Black holes …
