Chemical enrichment of the Perseus cluster core seen by XRISM/Resolve
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The intracluster medium (ICM) is rich in chemical elements, produced by core-collapse (SNcc) and Type Ia supernovae (SNIa) over the last 12 Gyr. Whereas cluster outskirts are…
The eROSITA Final Equatorial-Depth Survey (eFEDS): X-ray stacking analysis of Subaru's optically selected clusters spanning low richness regime
N. T. Nguyen-Dang, N. Ota, N. Okabe +17
This is the second paper in a series exploring the X-ray properties of galaxy clusters optically selected by the Subaru Hyper Suprime-Cam (HSC) survey, using data from the SRG/eROS…
Identification of low redshift groups and clusters of galaxies in the X-CLASS survey and the X-ray luminosity-temperature relation
Q. Moysan, F. Sarron, N. Clerc +16
Properties of the hot intracluster and intragroup medium are mostly set by the underlying gravitational potential well, although complex astrophysical processes at play during thei…
The life of central radio galaxies in clusters: AGN-ICM studies of eRASS1 clusters in the ASKAP fields
Angie Veronica, Thomas H. Reiprich, Florian Pacaud +35
The mechanical feedback from the central AGNs can be crucial for balancing the radiative cooling of the intracluster medium at the cluster centre. We aim to understand the relation…
Characterising galaxy cluster scaling relations as cosmic isotropy tracers using FLAMINGO simulations
Yujie He, Konstantinos Migkas, Joop Schaye +2
The standard cosmological model, CDM, assumes isotropy on large cosmic scales. However, recent studies using galaxy cluster scaling relations have reported an apparent an…
XMM-Newton follow-up of a sample of apparent low surface brightness galaxy groups detected in the ROSAT All-Sky Survey
Claudia Spinelli, Angie Veronica, Florian Pacaud +4
Galaxy cluster cosmology relies on complete and pure samples spanning a large range of masses and redshifts. In Xu et al. (2018) and Xu et al. (2022), we discovered an apparently n…
