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…
