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…
Constraint on Symmetric Teleparallel Gravity with Different Dark energy Parametrizations from DESI DR2 BAO Data
Rajdeep Mazumdar, Mrinnoy M. Gohain, Kalyan Bhuyan
We investigate the cosmological viability of symmetric teleparallel gravity, specifically the gravity model with a power-law form , in combination with two wide…
Gravitational Baryogenesis Constraints on Nojiri-Odintsov Gravity
Kalyan Malakar, Mrinnoy M Gohain, Kalyan Bhuyan
This paper focuses on exploring the imbalance between matter and antimatter via the gravitational baryogenesis mechanism within the framework of Nojiri-Odintsov gravity mode…
Dark Matter Surrounded Quartic Square-root Horndeski Black Hole: Thermodynamics, Optical Properties and Quasinormal Oscillations
Mrinnoy M. Gohain, Kalyan Bhuyan
In this work, we study a special form of Horndeski solutions, viz. quartic "square-root" Horndeski black hole immersed in a perfect-fluid dark-matter halo, by examining its thermod…
Unified Non-Singular Cosmology with Late-Time Acceleration through a Novel Parametrization of Bulk Viscosity Coefficient
Rajdeep Mazumdar, Mrinnoy M. Gohain, Kalyan Bhuyan
This work explores the influence of viscous fluids on cosmological dynamics within the framework of General Relativity. We introduce a novel time-dependent parametrization for the…
