Circular geodesics in Kerr-Newman-Kasuya black hole
Saeed Ullah Khan, Jingli Ren
This article explores the characteristics of ergoregion, horizons and circular geodesics around a Kerr-Newman-Kasuya black hole. We investigate the effect of spin and dyonic charge…
Particle dynamics around a dyonic charged black hole
Saeed Ullah Khan, Jingli Ren
In this article, we study the circular motion of particles and the well-known Penrose mechanism around a Kerr-Newman-Kasuya black hole spacetime. The inner and outer horizons, as w…
Shadow cast by a rotating charged black hole in quintessential dark energy
Saeed Ullah Khan, Jingli Ren
The existence of quintessential dark energy around a black hole has considerable consequences on its spacetime geometry. Hence, in this article, we explore its effect on horizons a…
Particle collisions in ergoregion of braneworld Kerr black hole
Saeed Ullah Khan, Misbah Shahzadi, Jingli Ren
This paper explores the neutral particle motion and collisional Penrose process in ergoregion of the braneworld Kerr black hole. We analyze the properties of event horizon, ergosph…
