Probing Quantum Gravity through Chaotic Orbits and Strong-Field Effects in Kerr Black Holes Embedded in Perfect Fluid Dark Matter

Shubham Kala, Sara Saghafi, M. Yousaf +4

The paper investigates how quantum‑gravity corrections and perfect fluid dark matter affect photon trajectories around a rotating (Kerr) black hole, using chaos diagnostics such as…

Light bending around the Kerr-Bertotti-Robinson black hole using material medium approach

Saswati Roy, Anshul Tapase, Shubham Kala +2

In this paper, we study the deflection of massless particles due to a rotating, axially symmetric Kerr-Bertotti-Robinson (KBR) black hole via; material medium approach. We explored…

Light Deflection and Greybody Bound Around a BTZ-ModMax Black Hole in Plasma Medium

Ritesh Pandey, Shubham Kala, Amare Abebe +2

We study the deflection of light in a homogeneous plasma medium around a BTZ-ModMax black hole, focusing on the effects of the ModMax nonlinear electrodynamics parameter and the co…

Gravitational lensing around a Kerr-Sen black hole in plasma background

Saswati Roy, Shubham Kala, Sayanika Modak +2

We investigate the gravitational lensing of massless particles around a Kerr-Sen black hole immersed in a magnetized, cold, pressureless plasma medium. Both homogeneous and inhomog…

Charged Black Holes in Bumblebee gravity with Global Monopole: Thermodynamics and Shadow

Faizuddin Ahmed, Shubham Kala, Edilberto O. Silva

In this paper, we perform a detailed study of the thermodynamic properties of a charged black hole in bumblebee gravity in the presence of a global monopole. We also analyze the op…

Shadow of Bonanno-Reuter Black Hole in Plasma Medium: Insights from EHT Sgr A* Observations

Shubham Kala

We investigate the properties of black hole shadows in the renormalization group (RG) improved Bonanno-Reuter spacetime, incorporating quantum gravitational corrections via the sca…
