Figure 1. Density field in the numerical simulation corresponding to a slice 100 h −1 Mpc thick
Figure 2. Left-hand panel: Voronoi cell volume versus mean neighbour separation, D IP , for all the haloes in the simulation
Figure 3. Filament detection method steps. Details of each step in text.
Fig. 4 shows four detected filaments in the simulation, where the halo density projected on to the xy plane is shown in a colour scale, the skeleton is shown as red lines, and the recentred skeleton as blue dashed lines
