An international team of astronomers has discovered a new giant structure in the Universe, which is a supercluster consisting of eight galaxy clusters. This is reported in an article published in the arXiv preprint repository.
Researchers analyzed the data obtained by the eROSITA X-ray telescope. The redshift of the new cosmological structure is 0.36, which corresponds to a distance of about four billion light years. Cluster eFEDS J093513.3 + 004746, located in the northern part of the supercluster, is the most massive and brightest of the eight. Its mass is estimated at 580 trillion solar masses.
The least massive clusters eFEDS J093546.4-000115 and eFEDS J093543.9-000334 have a mass of about 130 trillion solar masses. The masses of the other five clusters are estimated at 140 to 250 trillion solar masses.
Scientists have also identified radio halo combining two radio relics (diffuse radio sources of synchrotron origin ), which are located in the northern and southeastern regions of the northernmost clusters. Their presence indicates the process of merging of the cluster.
