Probing Nonlinear Logarithmic Kalb-Ramond Black Holes: Particle Dynamics, Epicyclic Oscillations and Thermodynamic Signatures
Aftab Ansari, Rajesh Kumar, Praveen Kumar Dhankar
In contrast to conventional linear coupling frameworks, the proposed work investigated the nonlinear effects that become more significant in the strong field regime of a black hole…
Observational Constraints on Gravity in the Presence of DBI-Essence Scalar Field
Mayur Mune, Praveen Kumar Dhankar, Goutam Manna +3
We investigate late-time cosmology in extended symmetric teleparallel gravity coupled to a Dirac-Born-Infeld (DBI) scalar field within gravity, where is the non-metric…
Cosmic Hysteresis in Reconstructed Bounce Models A Torsion-Based Thermodynamic Perspective
Aritra Sanyal, Praveen Kumar Dhankar, Albert Munyeshyaka +3
We investigate the emergence of cosmic hysteresis in cyclic and bouncing cosmologies within the framework of reconstructed gravity. In contrast to curvature-based modificati…
A Bayesian Statistical Study of Bianchi Type-I Universe in Modified Gravity
Mohit Thakre, Praveen Kumar Dhankar, Safiqul Islam +3
We have examined the cosmological actions of LRS (Locally Rationally Symmetric) Bianchi type-I universe model in gravity. For this, we have estimated the Hubble paramet…
Viscous Fluid Models of Cosmic Acceleration in FRW Spacetime Using MCMC Constraints
Mohit Thakre, Praveen Kumar Dhankar, Behnam Pourhassan +1
This study combines theoretical advancements with observational limitations to investigate the cosmological implications of a bulk viscous modified Chaplygin gas (MCG) in a Friedma…
Statistical Constraints on Anisotropic Bianchi-III Cosmology in -Gravity Using MCMC Methods
Mayur Mune, Praveen Kumar Dhankar, Safiqul Islam +3
Anisotropic Bianchi type-III cosmology is examined within the framework of f(R,T) gravity, where R denotes the Ricci scalar and T the trace of the energy-momentum tensor. In this w…
