Impact of the large-scale cosmic web on the X-ray emitting circumgalactic medium
Soumya Shreeram, Daniela Galárraga-Espinosa, Johan Comparat +9
The hot circumgalactic medium (CGM), probed by X-ray observations, plays a central role in understanding gas flows that drive a galaxy's evolution. While CGM properties have been w…
The hot circumgalactic medium in stacked X-rays: observations vs simulations
Skylar Grayson, Evan Scannapieco, Johan Comparat +5
Current cosmological simulations rely on active galactic nuclei (AGN) feedback to quench star formation and match observed stellar mass distributions, but models for AGN feedback a…
The eROSITA view on the halo mass-temperature relation: From low-mass groups to massive clusters
V. Toptun, P. Popesso, I. Marini +15
Galaxy groups and clusters are among the best probes of structure formation and growth in a cosmological context. Most of their baryonic component is dominated by the intracluster…

The impact of assembly history on the X-ray detectability of halos. From galaxy groups to galaxy clusters
I. Marini, P. Popesso, K. Dolag +15
Galaxy groups represent a significant fraction of the halo population, playing a crucial role in galaxy formation and evolution. However, their detection in X-rays remains challeng…
