Abstract: In this paper,we share the analysis results of Trio-Clusters of galaxies in the heart of Aquarius constellation.Super clusters are dense regions of the sky; close passages and mergers are highly probable. Thus, the line of sight images of A2550-A2554-A2556 looks like a trio-structure. We search for dynamical relations and the mutual gravitational effects on the structural evolutions by using ASCA, and Chandra archival data. The Newtonian gravitational binding criterion shows no clear bound by considering the potential and kinetic energy of the system. It looks like the Trio-Cluster is very close due to projection effects and hasn’t started its cosmic gravitational dance.
