Context. The quest for the cosmological parameters that describe our universe continues to
motivate the scientific community to undertake very large survey initiatives across the …

We present the first cosmological study of a sample of eROSITA clusters, which were
identified in the eROSITA Final Equatorial Depth Survey (eFEDS). In a joint selection on X …

ABSTRACT SPIDERS (The SPectroscopic IDentification of eROSITA Sources) is a large
spectroscopic programme for X-ray selected galaxy clusters as part of the Sloan Digital Sky …

ABSTRACT SPIDERS is the spectroscopic follow-up effort of the Sloan Digital Sky Survey IV
(SDSS-IV) project for the identification of X-ray selected galaxy clusters. We present our …

Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and
covers a total area of 50 square degrees distributed over two fields. It primarily aims at …

Context. The extended ROentgen Survey with an Imaging Telescope Array (eROSITA) on
board the Spectrum-Roentgen-Gamma (SRG) observatory is revolutionizing X-ray …

We report the scaling relations derived by fitting the X-ray parameters determined from
analyzing the XMM-Newton observations of 120 galaxy clusters in the Planck Early Sunyaev …

We present an X-ray point-source catalogue from the XMM-Large Scale Structure (XMM-
LSS) survey region, one of the XMM-Spitzer Extragalactic Representative Volume Survey …

We present our determination of the baryon budget for an X-ray-selected XXL sample of 136
galaxy groups and clusters spanning nearly two orders of magnitude in mass (M 500∼ 1013 …

Traditionally, galaxy clusters have been expected to retain all the material accreted since
their formation epoch. For this reason, their matter content should be representative of the …
