We study the motion of charged and spinning particles and photons in the 4D charged
Einstein-Gauss-Bonnet (EGB) black hole vicinity. We determine the radius of the innermost …

The motion of a magnetized particle orbiting around non-Schwarzschild black hole
immersed in an external uniform magnetic field is considered. The influence of deformation …

The neutral particle motion around rotating regular black hole that was derived from the
Ayón-Beato-García (ABG) black hole solution by the Newman-Janis algorithm in the …

In this paper, the Penrose process is used to extract rotational energy from regular black
holes. Initially, we consider the rotating Simpson–Visser regular spacetime, which describes …

Superradiance is a radiation enhancement process that involves dissipative systems. With a
60 year-old history, superradiance has played a prominent role in optics, quantum …

Konoplya and Zhidenko have proposed recently a rotating non-Kerr black hole metric
beyond General Relativity and make an estimate for the possible deviations from the Kerr …

This paper explores the dynamics of particles in higher dimensions. For this purpose, we
discuss some interesting features related to the motion of particles near a Myers–Perry black …

In this article, particle dynamics around charged rotating black holes with Weyl corrections is
discussed. First, the metric is studied for its horizon structure and scalar curvature invariants …

We have investigated the properties of the ergosphere and the energy extraction by Penrose
process in a Konoplya–Zhidenko rotating non-Kerr black hole spacetime. We find that the …

Localized energy estimates for the wave equation have been increasingly used to prove
various other dispersive estimates. This article focuses on proving such localized energy …
