Equatorial light bending around a Hairy Kiselev Black Hole
Shrishti Kukreti, Shubham Kala, Hemwati Nandan +2
We investigate the deflection angle of light rays confined to the equatorial plane of a Hairy Kiselev black hole. The analysis includes a thorough study of the horizon structure an…

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…

Null Geodesics, Thermodynamics, Weak Gravitational Lensing, and Black Hole Shadow Characteristics of a Frolov Regular Black Hole with Constraints from EHT Observations
Shubham Kala, Hemwati Nandan, Kush Maithani +2
In this paper, we investigate the properties of null geodesics, thermodynamics, gravitational lensing, and black hole shadows in the vicinity of a static regular Frolov black hole.…
