Astrophysical Signature and Optical Appearance of Weyl--Corrected Einstein--Maxwell Black Holes
Hassan Hassanabadi, Mrinnoy M. Gohain, Kalyan Bhuyan +1
In this work, we investigate the physics of charged black holes modified by Weyl corrections, which emerge from the non-minimal coupling between spacetime curvature and electromagn…
Viability Constraints on Baryogenesis in f (R, Lm, T) Gravity
Kalyan Malakar, Rajdeep Mazumdar, Mrinnoy M Gohain +1
Our study explores gravitational baryogenesis in the context of f(R, Lm, T) gravity, where R denotes the Ricci scalar, Lm represents the Lagrangian density of the matter field, and…
Dynamics of Geodesics in Non-linear Electrodynamics Corrected Black Hole and Shadows of its Rotating Analogue
Hari Prasad Saikia, Mrinnoy M. Gohain, Kalyan Bhuyan
We study the nature of particle geodesics around a non-linear electrodynamic black hole (NLED-BH) inspired by the confinement of a heavy quark-antiquark system, which reduces to Ma…
Shadows of a Non-Commutative Black Hole under the Influence of a Magnetized Plasma
Mrinnoy M. Gohain, Kalyan Bhuyan, Paragjyoti Chutia
We investigate the properties of the shadow cast by a black hole (BH) in a non-commutative spacetime surrounded by a plasma medium. BHs in a plasma environment can exhibit complex…
Frolov Black Hole Surrounded by Quintessence -- I: Thermodynamics, Geodesics and Shadows
Mrinnoy M. Gohain, Kalyan Bhuyan, Rajnandini Borgohain +3
The Frolov black hole (BH) is a charged extension of the Hayward BH, having regularity at the central point and an asymptotically Schwarzschild form for large values of …
Investigating Optical and Ring-Down Gravitational Wave Properties of a Rotating Black Hole in a Dehnen Galactic Dark Matter Halo
Mrinnoy M. Gohain, Dhruba Jyoti Gogoi, Kalyan Bhuyan +1
We present a comprehensive study of the optical and dynamical properties of a rotating black hole immersed in a Dehnen-type galactic dark matter halo, modeled by a double…
