Figure 2: The spatial distribution of haloes in regions of different density in a slice of thickness of 50 h-1Mpc (in the Z-direction); the Z interval is 150-200 h-1Mpc. The left panel shows the spatial distribution of haloes, the right panel shows the velocity vectors of haloes. Filled large circles denote haloes in the highest density environment (sample H23.1 in Table 1), filled small diamonds stand for the sample H23.2, open circles for the sample H23.3, and crosses denote haloes in the lowest density environment, sample H23.4. |
