It provides a comprehensive extension of the NGCG model, including energy transfer rates, diagnostic tools, and growth index evolution considering dark energy interactions.
Findings
Energy density change rates analyzed
Om diagnostic differentiates models effectively
Growth index evolution shows dark energy influence
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 diagnostic to differentiate the CDM 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.
