Modeling a Non-Singular Universe with Late-Time Acceleration through a Novel Inhomogeneous Barotropic Equation of State
Rajdeep Mazumdar, Mrinnoy M. Gohain, Kalyan Bhuyan
In this study, we investigated the effects of incorporating barotropic fluids on cosmological solutions within the general relativity (GR) framework. We proposed a modified version…

Cosmological Bounce Scenario with a Novel Parametrization of Bulk Viscosity
Rajdeep Mazumdar, Mrinnoy M. Gohain, Kalyan Bhuyan
In this work, we have studied how incorporating viscous fluids leads to exact bounce cosmological solutions in general relativity (GR) framework. Specifically, we propose a novel p…
