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…
Testing the Generalized Second Law in -Dimensional Cosmology: Holographic Entropy Bounds and Observational Constraints
Praveen Kumar Dhankar, Aritra Sanyal, Safiqul Islam +2
We investigate the validity of the Generalized Second Law (GSL) of thermodynamics in a -dimensional holographic cosmological model with a negative cosmological constant. Ado…
Constraints on multi-fluid cosmology in modified Gauss-Bonnet gravity models with different observational data sets
Praveen Kumar Dhankar, Albert Munyeshyaka, Aritra Sanyal +2
In the present work, we incorporate redshift-space distortion measurement to investigate the growth of large scale structure within the framework of multi-fluid cosmology in the co…
