Abstract

Superclusters represent the largest-scale environments where a number of galaxy clusters interact with each other through minor and major mergers and grow via accretion along cosmic filaments. We focus on the A3528 cluster complex in the core of the Shapley Supercluster (z ∼ 0.05). This chain includes three clusters: A3528 (which is itself composed of two sub-clusters, namely A3528N and A3528S), and A3532 and A3530, which present a mildly active dynamical state.
