European Physical Journal C: Particles and Fields, 2021 In the present paper, we investigate the dynamics of magnetized particles around magnetically and electrically Reissner–Nordström (RN) black hole. The main idea of the work is to distinguish the effects of electric and magnetic charges of the RN black ...

Shadow of the Kerr-like black hole
European Physical Journal C: Particles and Fields, 2022 The detailed study of horizon structure and the shadow cast by a Kerr-like black hole (BH) is performed. The trajectory of light rays forming the shadow of BH is found using the solutions of geodesic equation for the motion and effective potential of a ...

Gravitational Capture Cross-Section of Particles by Schwarzschild-Tangherlini Black Holes
Universe, 2021 We study the capture cross-section of massless (photon) and massive test particles by the Schwarzschild–Tangherlini black hole, which is a solution of pure general relativity in higher dimensional spacetime with R×SD−2 topology. It is shown that an extra

Charged particles and Penrose process near charged black holes in Einstein–Maxwell-scalar theory
European Physical Journal C: Particles and Fields, 2023 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 around the black hole are explored and the upper limit for the EMS theory ...

Dynamics of Test Particles and Twin Peaks QPOs around Regular Black Holes in Modified Gravity
Galaxies, 2021 In this work, we have presented a detailed analysis of the event horizon of regular black holes (BHs) in modified gravity known as MOG, the so-called regular MOG BH. The motion of neutral particles around the BH has also been explored.
