Thermodynamic Stability of a Viscous Variable Generalised Chaplygin Gas
D. Panigrahi, K. Kanjilal, Saibal Ray
We investigate the cosmological dynamics and thermodynamic properties of a viscous variable generalized Chaplygin gas (VVGCG) model in a spatially flat Friedmann--Lema^ıtre--Robert…
Emergent Universe Scenario in the Modified Chaplygin gas : Towards an Exact Solution and Observational Constraints
D. Panigrahi, S. Chatterjee, B. C. Paul
The Modified Chaplygin Gas (MCG) model is revisited as a unified framework for describing cosmic evolution. Due to the nonlinear field equations, exact solutions in cosmic time are…
Higher-Dimensional Cosmology in the Framework of Generalized Chaplygin Gas: An Approximation Method
D. Panigrahi, B. C. Paul, S. Chatterjee
We present a higher-dimensional cosmological model with a generalized Chaplygin-type gas to explain the late-time acceleration of the Universe. The model admits dimensional reducti…
An Alternative Approach to the Exact Solution of FRW-Type Spacetime with a Generalized Chaplygin Gas
D Panigrahi
The generalized Chaplygin gas model, characterized by the equation of state , is investigated within the framework of a Robertson-Walker spacetime. The resulti…
Studies of the Inhomogeneous Cosmology in Higher Dimensional space-time with a Cosmological Constant
D. Panigrahi, S. Chatterjee
We have studied the inhomogeneous cosmology in Kaluza-Klein spacetime with a positive cosmological constant in a dust dominated era (). Depending on the integration constant…
Accelerating Universe in Higher Dimensional Space Time : an alternative approach
D. Panigrahi, B. C. Paul, S. Chatterjee
We have discussed here a higher dimensional cosmological model and explained the recent acceleration with a Chaplygin type of gas. Dimensional reduction of extra space is possible…
