The majority of galaxies are organized into a hierarchy of associations called clusters, which, in turn, can form larger groups called superclusters. These larger structures are generally arranged into sheets and filaments, which surround immense voids in the universe.[9] Although it is not yet ...
Galaxies tend to cluster together, sometimes in small groups and sometimes in enormous complexes. Most galaxies have companions, either a few nearby objects or a large-scale cluster; isolated galaxies, in other words, are quite rare. Types of clusters Learn about galaxy clusters, superclusters, ...

Galaxy clusters are the largest structures in the universe, held together by gravity. They gather into superclusters, and our own Milky Way is part of the Local Group, which contains dozens of galaxies.

The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters. Only the estimated redshifts could be used, since t
