Clusters of Clusters
•Peebles (1980) schematic picture:
–Cloud of galaxies is basic unit, scale of 50 h-1 Mpc
–About 25% of galaxies in these clouds
–All Abell Clusters are members of clouds (with about 2 per cloud), and contain about 25% of the galaxies in a cloud are in Abell Clusters (superclusters occur when several AC combine)
–Remaining 75% follow galaxy-galaxy function
–In terms of larger structures, galaxies hug the walls of the voids, clusters at the intersections of the cell walls.
