Evolution of total projected density on (x, y) plane for halo 3 of the ‘CDM’ simulations with L = 25 Mpc h⁻¹. This figure is analogous to Fig. 7 except that the times considered here are slightly different and that there is one extra panel in the third column corresponding to present time, a = 1. In the third column of panels, the volume projected is larger in order to have a better view of the various structures at play.
