Structure and dynamics of the Shapley Supercluster

摘要: We present results of our wide-field redshift survey galaxies in a 285 square degree region the Shapley Supercluster (SSC), based on set 10 529 velocity measurements (including 1201 new ones) 8632 obtained from various telescopes and literature. Our data reveal that main plane SSC (v ≈ 14 500 km s −1 ) extends further than previous estimates, filling whole extent 12 degrees by 30 sky (30 × 75 h Mpc). There is also connecting structure associated with slightly nearer Abell 3571 cluster complex 000 ). These seem to link two previously identified sheets establish connection third one at v = 15 near RA 13 . They tend fill gap between foreground Hydra-Centaurus more distant SSC. In range (9000 < cz 18 ), we found redshift-space overdensities bj 17. 5o f� 5.4 over 225 central � 3.8 192 excluding rich clusters. Over large survey, find intercluster make up 48 per cent observed and, accounting for different completeness, may contribute nearly twice as much mass galaxies. this paper, discuss completeness catalogue, morphology supercluster, global overdensity, some properties individual galaxy clusters Supercluster.
