Results from current X-ray selected galaxy cluster samples and way forward to eROSITA cosmology
1Argelander-Institut für Astronomie, Universität Bonn, Auf dem Hügel 71, 53121 Bonn
The latest results from detailed X-ray follow-up observations of large X-ray selected galaxy cluster samples are presented. A reanalysis of the ROSAT All-Sky Survey with a source detection method optimized for very extended sources is discussed. A new test to study the cosmological isotropy of the cluster population is introduced. An outlook on expected cosmological constraints from eROSITA, in particular on neutrino masses, is given.
