Scientific paper

The multifractal properties of nonlinear gravitational clustering are studied by applying several different generalized dimension estimators to evolving cosmological N-body simulations. Three different initial spectra, a CDM spectrum and two scale-free spectra with n = 1 and n = -2, and different biasing levels are considered. The main result of the study is that nonlinear clustering, associated with the small-scale gravitational evolution and with the high peaks of the underlying density field, is always characterized by precise scaling properties. In particular, structures arising at the nonlinearity scales closely resemble a bifractal, while at larger scales a transition toward homogeneity is observed.
