Results from the first Erosita X-Ray sky survey
Results from the first Erosita X-Ray sky survey show consistency where previous measurements of the structure of the universe indicated inconsistencies.
The analysis of how galaxy clusters, the largest objects in the Universe, evolve over cosmic time has yielded precise measurements of the total matter content and its clumpiness, report scientists of the German eROSITA consortium, led by the Max Planck Institute for Extraterrestrial Physics and with participation of the University of Bonn. The results affirm the standard cosmological model and alleviate the so-called S8 tension, while at the same time offering insights into the elusive neutrinos' mass. The analysis is based on one of the largest catalogues of galaxy clusters and superclusters, also released today. An important pillar in the analysis is the ``weighing’’ of the discovered galaxy clusters, where the University of Bonn contributed in a major way.
Cluster initiative "Our dynamic universe" into the next round
The cluster initiative "Our dynamic Universe" was given the green light to apply for funding as part if the Excellence Initiative of the German government and federal states.
This was announced by the German Reserarch Foundation (DFG) and the German Council of Science and Humanities Feb. 2nd 2024.
