Scientists have been looking at the data from the eROSITA Final Equatorial Depth Survey (eFEDS) and now, they have found a new supercluster. The newly found pattern has a cluster of eight galaxies. Experts have said that it has many structures of a wide range of masses. From huge and thick bunches of galaxies to low-density bridges, filaments, sheets of matter, superclusters are one of the largest formations in the universe, said the experts. Scientists have said that finding and studying these superclusters will help them understand the origin and evolution of huge cosmic filaments in a better way. A team of experts from the Max Planck Institute for Extraterrestrial Physics at Garching Germany has found out the new supercluster. It has been found during the Performance Verification (PV) phase of the eFEDS.
Experts have observed the 140-deg2 eFEDS field, which has been found to a nominal depth of around 2 ks during the Performance Verification (PV) phase. They have said that in this field, they have found a never ever seen supercluster. This supercluster has a series of eight galaxy clusters at a redshift of 0.36. The findings of the study have shown that the northernmost clusters of this pattern are undergoing an off-axis major merger activity. As per the optical and X-ray data, it is a triple integration system with a dual merger and a pre-merger. The cluster designated eFEDS J093513.3+004746, which resides in the northern part of the supercluster is the most gigantic and bright one out of the eight clusters. Scientists have claimed that it is one of the biggest and most glowing clusters in the entire eFEDS. The mass of this cluster has been calculated to be 580 trillion solar masses.
Most tiny clusters of this supercluster are eFEDS J093546.4-000115 and eFEDS J093543.9-000334. The masses of these clusters have been measured to be around 130 trillion solar masses. Experts have said that the masses of the remaining five clusters are between 140 to 250 trillion solar masses. The data has shown that there are two radio relics in the north and southeast areas of the northernmost clusters along with a stretched out radio halo. This radio halo helps in the ongoing merger activity state. The study has revealed that the X-ray properties of the eight clusters making the new supercluster are like the common eFEDS cluster population. Experts have said that their morphological traits match with the sample of more than 300 clusters, which have been found by eFEDS. The findings of the study have been released on the arXiv pre-print server.
