Circular motion around a regular rotating Hayward black hole

Saeed Ullah Khan, Jingli Ren, Javlon Rayimbaev

In this article, we explore the geodesics motion of neutral test particles and the process of energy extraction from a regular rotating Hayward black hole. We analyse the effect of…

Shadow cast and center of mass energy in a charged Gauss-Bonnet-AdS black hole

Muhammad Zahid, Saeed Ullah Khan, Jingli Ren

This work is devoted to the exploration of shadow cast and center of mass energy in the background of a 4-dimensional charged Gauss-Bonnet AdS black hole. On investigating particle…

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…

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…
