Baryonic assembly bias in X-ray-selected galaxy groups and clusters: insights from the Magneticum simulation
Ilaria Marini, Tiago Castro, Paola Popesso +5
Galaxy groups and clusters trace the large-scale matter distribution, with their clustering usually interpreted mainly as a function of halo mass. Yet, at fixed mass, their baryoni…
Detecting Galaxy Groups and AGNs populating the local Universe in the eROSITA era
I. Marini, P. Popesso, G. Lamer +14
The eROSITA will deliver an unprecedented volume of X-ray survey observations, 20-30 times more sensitive than ROSAT in the soft band (0.5-2 keV) and for the first time imaging in…
The SRG/eROSITA All-Sky Survey: Constraints on AGN Feedback in Galaxy Groups
Y. E. Bahar, E. Bulbul, V. Ghirardini +25
We investigate the impact of AGN feedback, on the entropy and characteristic temperature measurements of galaxy groups detected in the SRG/eROSITA's first All-Sky Survey (eRASS1) t…
The X-ray invisible Universe. A look into the halos undetected by eROSITA
P. Popesso, A. Biviano, E. Bulbul +15
The paper presents the analysis of optically selected GAMA groups and clusters in the SRG/eROSITA X-ray map of eFEDS (eROSITA Final Equatorial Depth Survey), in the halo mass range…
4MOST Consortium Survey 5: eROSITA Galaxy Cluster Redshift Survey
A. Finoguenov, A. Merloni, J. Comparat +11
Groups and clusters of galaxies are a current focus of astronomical research owing to their role in determining the environmental effects on galaxies and the constraints they provi…
Weak lensing observations of potentially X-ray underluminous galaxy clusters
J. P. Dietrich, A. Biviano, P. Popesso +3
Optically selected clusters of galaxies display a relation between their optical mass estimates and their X-ray luminosities Lx that has a large scatter. A substantial fraction of…
