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…
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…
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…
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…
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.…
