Clustering of Galaxy Clusters in CDM Universes
J. M. Colberg, S. D. M. White, N. Yoshida +9
We use very large cosmological N--body simulations to obtain accurate predictions for the two-point correlations and power spectra of mass-limited samples of galaxy clusters. We co…
Experimental Cosmic Statistics II: Distribution
István Szapudi, Stéphane Colombi, Adrian Jenkins +1
Colombi et al. 1999 (paper I) investigated the counts-in-cells statistics and their respective errors in the CDM Virgo Hubble Volume simulation. This extremely large -body ex…
Experimental Cosmic Statistics I: Variance
Stéphane Colombi, István Szapudi, Adrian Jenkins +1
Counts-in-cells are measured in the CDM Virgo Hubble Volume simulation. This large N-body experiment has 10^9 particles in a cubic box of size 2000 h^{-1} Mpc. The unprecedented…
The Dependence in the Equations of Motion
Adi Nusser, Jörg M. Colberg
We show that the equations of motion governing the evolution of a collisionless gravitating system of particles in an expanding universe can be cast in a form which is almost indep…
