Role of viscous fluid in FLRW model with observational constraints
Anirudh Pradhan, G. K. Goswami
In this study, we investigate the role of bulk viscosity in the evolution of a spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) universe dominated by dust. We parameterize…
Observational Constraints and Geometric Diagnostics of Barboza-Alcaniz and Logarithmic Dark Energy Parametrizations
Archana Dixit, Saurabh Verma, Anirudh Pradhan +1
This study investigates and compares two prominent two-dimensional dark energy (DE) parameterizations: Barboza-Alcaniz (BA) and Logarithmic forms by comparing them with a comprehen…
Dynamical Oscillations in Dark Energy: Joint Constraints on the CDM Model from DESI, OHD, and Supernova Samples
Manish Yadav, Archana Dixit, M. S. Barak +1
In this study, we investigate the oscillatory dark energy model based on the DESI BAO data together with OHD, Pantheon Plus, and SH0ES measurements. We exami…
An Accelerating Flat FLRW Model with Observation Constraints and Dynamic
G. K. Goswami, Anirudh Pradhan
In this paper, we explore power law solution of FLRW universe model that is associated with a variable cosmological term as a linear function of $\frac{\ddot{a}}{a}, (\frac{…
Holographic dark energy through Kaniadakis entropy in non flat universe
Suresh Kumar P, Bramha Dutta Pandey, Umesh Kumar Sharma +1
By extending the standard holographic principle to a cosmological framework and combining the non-flat condition with the Kaniadakis entropy, we construct the non-flat Kaniadakis h…
New Tsallis Holographic Dark Energy
Bramha Dutta Pandey, Suresh Kumar P, Pankaj +1
Tsallis entropy is a generalization of the Boltzmann-Gibbs entropy in statistical theory which uses a parameter to measure the deviation from the standard scenario quantitative…
