Abstract

Dark matter, the “glue” that holds our Universe bound, remains a mystery. A key question to understand its nature is whether dark matter particles can interact with each other in more ways than only through gravity. Using X-ray data of galaxy clusters, scientists revealed whether self-interacting dark matter could be the answer to one of the unsolved problems in cosmology.
