An article accepted for publication in the journal “Astronomy & Astrophysics” reports the observations of an interaction within the Shapley supercluster, one of the largest known structures in the universe, with collisions between galaxies within it. A team of researchers used in particular observations conducted with three radio telescopes: the Australian ASKAP, the South African MeerKat, and the Indian GMRT. That data was complemented with optical frequency observations conducted with the VST in Chile and X-ray observations with NASA’s XMM-Newton space telescope. Galaxy merger processes are occurring among relatively small groups but offer information on consequences at various scales, with influences even on large structures of galaxy clusters.
