A recent study has revealed a new phenomenon at the core of galaxy clusters: large-scale cold fronts. These cold fronts are believed to form when a vast amount of gas is stripped away from galaxies as they move through the cluster’s hot atmosphere. The gas that is stripped away is then pushed outward and forms a large cold wave that radiates from the cluster’s core. This wave is much larger and cooler than the surrounding hot atmosphere, and it has been observed to move away from the cluster’s core at speeds of up to several hundred kilometers per second. This study provides new insight into how matter and energy are distributed and exchanged in galaxy clusters, and it could help improve our understanding of the formation and evolution of these massive structures.
