Even more intriguing about the discovery is that the researchers found evidence of mergers between the galaxies with the cluster. The off-center nature of the radio halo has also provided scientists with quite a puzzle, as most radio signals of this sort act more in line with the gas and dust that make up the “intracluster medium.”
