The SRG/eROSITA All-Sky Survey. Early dark energy and Hubble constant from the cluster mass function

The evolution of the mass function of massive galaxy clusters is a well-established cosmological probe. Using the eROSITA X-ray instrument on board the (SRG) mission, the western Galactic hemisphere of eROSITA's first All-Sky Survey (eRASS1) delivers a uniformly selected and secu...

The SRG/eROSITA all-sky survey. X-ray scaling relations of galaxy groups and clusters in the western Galactic hemisphere

The soft X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) mission, extended ROentgen Survey with an Imaging Telescope Array (eROSITA), has produced the largest sample to date of galaxy groups and clusters detected via their intracluster and intragroup medium emission. S...
