Average X-ray properties of galaxy groups. From Milky Way-like halos to massive clusters

P. Popesso, I. Marini, K. Dolag +20

This study examines the average X-ray properties of massive halos at z< 0.2, covering the largest halo mass range to date, from Milky Way-like halos to massive clusters. The analys…

The hot gas mass fraction in halos. From Milky Way-like groups to massive clusters

P. Popesso, A. Biviano, I. Marini +21

By using eROSITA data in the eFEDS area, we provide a measure of the hot gas fraction vs. halo mass relation over the largest halo mass range, from Milky Way-sized halos to massive…

The perils of stacking optically selected groups in eROSITA data. The Magneticum perspective

P. Popesso, I. Marini, K. Dolag +23

Hydrodynamical simulation predictions are often compared with observational data without fully accounting for systematics and biases specific to observational techniques. Using the…

Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters

Pengfei Li, Ang Liu, Matthias Kluge +13

The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…

X-ray and optical analysis of the distant, merging double cluster SPT-CLJ2228-5828, its gas bridge, and shock front

K. Migkas, M. W. Sommer, T. Schrabback +15

Galaxy cluster mergers are excellent laboratories for studying a wide variety of different physical phenomena. Such a unique system is the distant SPT-CLJ2228-5828 cluster merger l…

The SRG/eROSITA All-Sky Survey : Constraints on the structure growth from cluster number counts

E. Artis, E. Bulbul, S. Grandis +29

Beyond testing the current cosmological paradigm, cluster number counts can also be utilized to investigate the discrepancies currently affecting current cosmological measurements.…
