AbstractThe nature and extent of the Great Attractor (GA) has been the subject of much debate in the past decade, partly due to the fact that a large fraction of the GA overdensity is hidden by the southern Milky Way. Based on our deep optical galaxy search behind the southern Milky Way and a subsequent redshift survey we discovered that the Norma cluster (ACO 3627) in the GA region is a very massive cluster of galaxies. The cluster is comparable in size, richness and mass to the Coma cluster. It is located at the intersection of two distinct large structures, the Centaurus Wall and the Norma Supercluster. The velocity flow fields in the GA region are most likely caused by the confluence of these two massive structures where the Norma cluster constitutes its previously unseen but predicted core. The possibility that another, heavily obscured and yet uncharted rich cluster might form part of the GA overdensity is also discussed.
