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…
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…
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…
New Agegraphic Dark Energy Driven Reconstruction of \boldmath{} Gravity and its Cosmological Implications
Rajdeep Mazumdar, Kalyan Malakar, Mrinnoy M. Gohain +1
In this work, we perform reconstruction of \( f(Q) \) gravity inspired by the New Agegraphic Dark Energy (NADE) model, aiming to account for the Universe's late time acceleration w…
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…
