The MX northern Abell cluster survey II: the Abell/ACO cluster redshifts and spatial analyses.


Abstract (from CDS):

The MX Northern Abell Cluster Survey II is the final stage of a program designed to observe rich Abell clusters with m10≤17.0. We present 1542 new galaxy redshifts within 117 R≥1 Abell cluster fields that have 16.9≤m10≤17.0, 0h≤α≤24h, -17°≤δ≤90°, and|b|≥30°. Of the 117 clusters observed for the MX Survey II, 105 new cluster redshifts were obtained with an average of eight cluster member galaxy redshifts. We update the m10-z estimator for Abell clusters and calculate the spatial number density of Abell clusters to be n{d1}c=(8.25±1.9)x10–6 h3 Mpc–3 within z=0.10. All R≥1 Abell and ACO clusters with measured redshifts were combined to calculate the two-point spatial correlation function ξ(r)=(r/ro)γ for the largest complete sample of rich clusters to date. We find 18.6≤ro≤21.0 h–1 Mpc and -2.03≤γ≤-1.95. The slope and correlation length are very robust and remain unaffected by the exclusion of compact and dense superclusters or by accounting for line-of-sight anisotropies, which are explained by the existence of three observationally confirmed and extended superclusters.
