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. Scaling relations between the intrinsic p...

CHEX-MATE: Density profile reconstruction in galaxy clusters

We investigated the reconstruction of the intra-cluster medium radial density profiles in galaxy clusters, focusing on the impact of cluster morphology, dynamical state, and methodological choices, within the framework of the ̧hxmate project. Using a sample of 109 simulated galaxy clusters analysed along 40 independent...
