Figure 1

Auto-correlation functions of the density fluctuation in a cosmological box of 3 Gpc sampled with 2 trillion particles simulation at various epoch indicated by the redshift. Dashed lines indicate the statistical errors due to the finite volume of the simulation as well as shot noise. The accuracy of these theoretical predictions is far below the percent level on almost all scales.
