The full iron budget in simulated galaxy clusters: The chemistry between gas and stars
Veronica Biffi, Elena Rasia, Stefano Borgani +5
Heavy chemical elements such as iron in the intra-cluster medium (ICM) of galaxy clusters are a signpost of the interaction between the gas and stellar components. Observations of…
Encyclopedia Magneticum: Scaling Relations from Cosmic Dawn to Present Day
Klaus Dolag, Rhea-Silvia Remus, Lucas M. Valenzuela +10
Galaxy and halo scaling relations, connecting a broad range of parameters, are well established from observations. The origin of many of these relations and their scatter is still…
How the cool-core population transitions from galaxy groups to massive clusters: A comparison of the largest Magneticum simulation with eROSITA, XMM-Newton, Chandra and LOFAR observations
Justo Antonio Gonzalez Villalba, Klaus Dolag, Veronica Biffi
Our aim is to understand how the interplay between AGN feedback and merge processes can effectively turn cool-core galaxy clusters into hot-core clusters in the modern universe. Ad…
Average energy of the X-ray spectrum as a model-independent proxy for the mass of galaxy clusters
A. Kruglov, I. Khabibullin, N. Lyskova +2
Temperature of the hot gas in galaxy clusters is known to be a reliable proxy for their total gravitating mass, allowing one to use spectroscopic X-ray observations for halo mass f…
