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…

Non-Equatorial Deflection of Light due to Kerr-Newman Black Hole: A Material Medium Approach
Saswati Roy, Shubham Kala, Prasanjit Ghosh +2
We explored the effect of space-time geometry on the trajectory of light rays in the context of a charged, rotating black hole. We derived an analytical expression for the deflecti…

Deflection of Light due to Kerr Sen Black Hole in Heterotic String Theory using Material Medium Approach
Saswati Roy, Shubham Kala, Atanu Singha +2
The deflection of light in the gravitational field of a massive body can be analyzed through diverse theoretical approaches. The null geodesic approach is commonly employed to calc…
