Abstract

Since the 1980s, we have known that the Local Group of galaxies is moving at a velocity of 366 ± 125 km/s in the direction of Centaurus. In this region, the well-known Shapley supercluster of galaxies (SSC) consists of many clusters and groups of galaxies in the redshift range 0.04 <z <0.055. An international collaboration has highlighted this greatest matter concentration in the local Universe, less than 500 million light years from us. The SSC may be able to account for half of the sought for ‘Great Attractor’...
