The large-scale structure formation in an expanding universe

In this paper, we analyze the effects of expansion on large scale structure formation in our Universe. We do that by incorporating a cosmological constant term gravitational partition function. This function with is used for analyzing thermodynamics system. virial system, and obtain its equation state. It observed generalization state like Van der Waals equation. also phase transition system using mean field theory. construct cosmic energy galaxies, discuss consequences. distribution compare results obtained paper observational data.
