The sky area where the eROSITA instrument identified the eight galaxy clusters that form the new supercluster

An article to be published in the journal “Astronomy & Astrophysics” reports the discovery of a galaxy supercluster. A team of researchers led by Vittorio Ghirardini of the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, analyzed data from the eFEDS survey conducted with the Spektr-RG space telescope’s eROSITA instrument identifying a structure composed of eight different galaxy clusters. Follow-up observations with the LOFAR and uGMRT radio telescopes made it possible to confirm that it’s a supercluster thanks to the identification of filaments that unite the various galaxies. The possibility of improving our knowledge of the cosmic filament web is one of the reasons why it’s important to find these superclusters.
