The Shapley Supercluster is widely recognised as the most massive gravitationally bound structure in the local universe.The supercluster is made up of 11 galaxy clusters and groups and extends across ~ 260 megaparsecs. At its core, which this paper focuses on, are five clusters. This core hosts several radio haloes,which are caused by shock-heated gas from the Intracluster medium (ICM) and is evidence of ongoing cluster merger activity. This supercluster core is highly dynamically active (full of cluster-cluster mergers), which could influence the evolution of galaxies within the core. This paper examines the evolution of galaxies by observing the cold gas within galaxies (i.e. the neutral hydrogen) and compares several galaxy properties to do so (see also: this previous Astrobite featuring ram-pressure stripped galaxies in the Shapley Supercluster).

What if JWST’s early massive galaxies are not overestimated, but underestimated? A bottom-heavy IMF could hide tons of mass in faint stars.
