The impact of strong feedback on galaxy group scaling relations
D. Eckert, R. Seppi, J. Braspenning +16
Feedback from active supermassive black holes alters the distribution of matter in the Universe by injecting energy in the neighbouring hot gaseous medium, which leads to ejection…
In medio stat virtus: enrichment history in poor galaxy clusters
G. Riva, S. Ghizzardi, S. Molendi +6
The enrichment history of galaxy clusters and groups remains far from being fully understood. Recent measurements in massive clusters have revealed remarkably flat iron abundance p…
Unveiling Chemical Enrichment in the Abell 2029 Core with XRISM, XMM-Newton, and Chandra
Arnab Sarkar, Eric D. Miller, Brian McNamara +6
We present new measurements of the chemical abundance pattern in the core of the nearby galaxy cluster Abell~2029, based on XRISM observations with Resolve (37 ks) and Xtend (500 k…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction
M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31
In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…
Measuring the Temperature of Extremely Hot Shock-Heated Gas in the Major Merger MACS J0717.5+3745 With Relativistic Corrections to the Sunyaev-Zel'dovich Effect
Benjamin J. Vaughan, Jack Sayers, Locke Spencer +10
The conversion of gravitational potential to kinetic energy results in an intracluster medium (ICM) gas with a characteristic temperature near 10 keV in the most massive galaxy clu…
XRISM Reveals Complex Multi-Temperature Structures in the Abell 2029 Galaxy Cluster
Arnab Sarkar, Eric Miller, Naomi Ota +9
We present 500 ks XRISM observations covering the central and two northern regions of the Abell 2029 galaxy cluster. Resolve enables us to distinguish multiple emission lines…
CHEX-MATE: Cluster Multi-Probes in Three Dimensions (CLUMP-3D) II. Combined Gas and Dark Matter Analysis from X-ray, SZE, and WL
Adriana Gavidia, Junhan Kim, Jack Sayers +15
Under the standard model of hierarchical structure formation, the overall geometry of galaxy clusters is better described by a triaxial ellipse than a sphere. As a result, applying…
CHEX-MATE: New detections and properties of the radio diffuse emission in massive clusters with MeerKAT
M. Balboni, F. Gastaldello, A. Bonafede +18
Modern radio telescopes are revolutionising our understanding of non-thermal phenomena in galaxy clusters, collecting large samples of extended sources with unprecedented sensitivi…
Extreme AGN feedback in the fossil galaxy group SDSSTG 4436
D. Eckert, F. Gastaldello, L. Lovisari +20
Supermassive black hole feedback is the currently favoured mechanism to regulate the star formation rate of galaxies and prevent the formation of ultra-massive galaxies ($M_\star>1…
Modelling the selection of galaxy groups with end to end simulations
R. Seppi, D. Eckert, A. Finoguenov +13
Feedback from supernovae and AGN shapes galaxy formation and evolution, yet its impact remains unclear. Galaxy groups offer a crucial probe, as their binding energy is comparable t…
CHEX-MATE: The Impact of Triaxiality and Orientation on Planck SZ Cluster Selection and Weak Lensing Mass Measurements
H. Saxena, J. Sayers, A. Gavidia +17
Galaxy cluster abundance measurements are a valuable tool for constraining cosmological parameters like the mass density () and density fluctuation amplitude (). Wide are…

CHEX-MATE: exploring the kinematical properties of Planck galaxy clusters
Lorenzo Pizzuti, Rafael Barrena, Mauro Sereno +19
We analyse the kinematical properties of the CHEX-MATE (Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation) galaxy c…
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…
