Super Cluster -

(Einasto et al., 2018/2026): This series of studies examines the A2142 supercluster to show how superclusters act as "unique laboratories" for galaxy evolution. It provides evidence that these structures are actively collapsing even in the presence of dark energy.

(Tully et al., 2014): This landmark paper redefined our home supercluster, naming it Laniakea (Hawaiian for "immeasurable heaven"). It used a new technique based on the flow of galaxies rather than just their positions to map the boundaries of this 500-million-light-year-wide structure. Discovery of a massive supercluster system at Super Cluster

Below are several foundational and helpful papers that have defined or significantly advanced our understanding of these cosmic structures: (Einasto et al

(2024): This recent paper leverages a massive X-ray galaxy cluster sample to present the largest-ever catalog of X-ray superclusters, providing a vital tool for exploring the large-scale structure of the universe. It used a new technique based on the

(Lietzen et al., 2016): This paper details the discovery of the , one of the most massive and extended systems of superclusters ever found, containing over 800 galaxies.

(Sankhyayan et al., 2023): A comprehensive modern effort to identify and characterize supercluster properties using the WHL cluster catalog and the SDSS, helping to refine the standard cosmological model ( Λcap lambda Key Facts about Superclusters:

In the context of astronomy, a is a massive group of galaxy clusters that ranks among the largest known structures in the universe.
