Interacting Modified Variable Chaplygin Gas in a Non-flat Universe

We have presented a more generalized model of interacting Chaplygin gas. The effective equation of states corresponding to matter and dark energy have been derived in this generalized model. Moreover, the case of phantom energy arises by putting some constraints on the parameters involved.

Interacting New Generalized Chaplygin Gas

We have presented a model in which the new generalized Chaplygin gas interacts with matter. We find that there exists a stable scaling solution at late times in the evolution of the universe. Moreover, the phantom crossing scenario is also observed in this model.

Density Evolution in the New Modified Chaplygin Gas Model

In this paper, we have considered new modified Chaplygin gas (NMCG) model which interpolates between radiation at early stage and ΛCDM at late stage. This model is regarded as a unification of dark energy and dark matter (with general form of matter). We have derived the density parameters from the equation of motion for the interaction between dark energy and dark matter. Also we have studied ...

Variable Modified Chaplygin Gas and Accelerating Universe

In this letter, I have proposed a model of variable modified Chaplygin gas and shown its role in accelerating phase of the universe. I have shown that the equation of state of this model is valid from the radiation era to quiessence model. The graphical representations of statefinder parameters characterize different phase of evolution of the universe. All results presented in the letter concer...

Role of Modified Chaplygin Gas in Accelerated Universe

Recent observations of the luminosity of type Ia supernovae indicate [1, 2] an accelerated expansion of the universe and lead to the search for a new type of matter which violate the strong energy condition ρ + 3p < 0. The matter consent responsible for such a condition to be satisfied at a certain stage of evolution of the universe is referred to as dark energy. There are different candidates ...
