The Extended Analysis On New Generalized Chaplygin Gas

Cosmology and Nongalactic Astrophysics 2015-06-12 v2

Abstract

We will extend the study of the new generalized Chaplygin gas (NGCG) based on [JCAP 0601(2006)003]. Concretely, we will not only discuss the change rates of the energy densities and the energy transfer of this model, but also perform the OmOm diagnostic to differentiate the Λ\LambdaCDM model from the NGCG and the GCG models. Furthermore, in order to consider the influence of dark energy on the structure formation, we also present the evolution of growth index in this scenario with interaction.
