[30.02] Spatial Analyses of a Complete Sample of Rich Abell/ACO Clusters to z=0.14

C.J. Miller (UMaine)

Galaxy clusters act as excellent mass tracers in our local Universe. They are bright, contain hundreds of galaxies, and are easy to observe. The most recognized galaxy cluster catalogs are those of Abell (1958) and Abell, Corwin and Olowin (1989-ACO). I will present the results of a new survey of Abell/ACO cluster redshifts that extends our knowledge of the large-scale mass distribution to a redshift of z = 0.14. The volume of the Universe traced by this survey is four times larger than any of its predecessors. The large number of clusters within the survey boundaries (~560) as well as the large volume traced, allow for statistical analyses on scales never before probed. I will present the cluster power spectrum to scales approaching 1000h-1Mpc.

I will also demonstrate the high-level of completeness for this survey, which allows one to study the effects of large-scale structure on internal cluster properties. I will then summarize some recent collaborative efforts which show that (1) Wide-Angle Tail radio jets are ``blown'' in the direction of the local large-scale axis; (2) High dM/dt cooling flow clusters reside in crowded environments; (3) Clusters with close near-neighbors are also close to the fundamental plane created from Lo, Lx and Ro.
