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…
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…
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…
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.…
