Uncovering the secret law of the evolution of galaxy clusters

Analysis of gravitational lensing data by an international research team reveals that the evolution of galaxy clusters is dictated by a surprisingly simple law, which clearly shows that they are still growing

Using observational data from the Hubble Space Telescope and the Subaru Telescope, the size and mass of galaxy clusters have precisely been measured. The research team analyzed those data and found a simple law that regulates the growth of the clusters. They also showed that the clusters are still young and growing. The newfound law will serve as a tool to clarify the evolutionary history of clusters and the universe.
