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…
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…
Tolman-Bondi-Lemaître spacetime with a generalised Chaplygin gas
D. Panigrahi, S. Chatterjee
The Tolman-Bondi-Lemaître type of inhomogeneous spacetime with generalised Chaplygin gas equation of state given by is investigated where is a constant. W…
Viability of Variable Generalised Chaplygin gas - a thermodynamical approach
D. Panigrahi, S. Chatterjee
The viability of the variable generalised Chaplygin gas (VGCG) model is analysed from the standpoint of its thermodynamical stability criteria with the help of an equation of state…
