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…

Circular Motion and Energy Extraction in a Rotating Black Hole
M. Shahzadi, Z. Yousaf, Saeed Ullah Khan
This paper explores the circular geodesics of neutral test particles on an equatorial plane around a rotating black hole. After using equations of motion of scalar-tensor-vector gr…

Particle Dynamics Near Kerr-MOG Black Hole
M. Sharif, Misbah Shahzadi
This paper explores the dynamics of both neutral as well as charged particles orbiting near a rotating black hole in scalar-tensor-vector gravity. We study the conditions for the p…
