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…

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…
