Snapshots of three subhalo-poor halos (top) and three subhalo-rich halos (bottom). Starting from the left, epoch are z = 6.04, z = 3.21, z = 1.04, and z = 0, width are 0.8 Mpc, 1.6 Mpc, 1.6 Mpc, and 0.8 Mpc. The center of snapshot is defined as the center of mass of particles which lie in the halo virial radius at z = 0.0.
