N-body simulations for structure formation from random initial conditions

摘要: We present the results of an extensive series high-performance simulations evolution self-gravitating systems with periodic boundary conditions. The main aim project is to investigate role gravitation and initial conditions into following toward a metastable equilibrium, in way such distinguish various ingredients overall dynamics. In particular, we compare spatially infinite embedded expanding universe that static frame. discuss differences similarities several statistical quantities, as density profiles clusters two point autocorrelation function.
