Galaxy cluster temperature maps from joint X-ray and SZ maps with The Three Hundred hydrodynamical simulations
R. Wicker, M. De Petris, A. Ferragamo +8
Galaxy clusters can be used as powerful cosmological probes, provided one can obtain accurate mass estimates, which requires a precise knowledge of the underlying astrophysics of g…
CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction
M. Muñoz-EcheverrÃa, 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…
Deriving accurate galaxy cluster masses using X-ray thermodynamic profiles and graph neural networks
Asif Iqbal, Subhabrata Majumdar, Elena Rasia +4
Precise determination of galaxy cluster masses is crucial for establishing reliable mass-observable scaling relations in cluster cosmology. We employ graph neural networks (GNNs) t…
The origin of the intra-cluster light in The Three Hundred simulations
A. Contreras-Santos, A. Knebe, W. Cui +9
We investigate the origin and formation mechanisms of the intra-cluster light (ICL) in The Three Hundred simulations, a set of 324 hydrodynamically resimulated massive galaxy clust…
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…
The Atacama Cosmology Telescope: A census of bridges between galaxy clusters
G. Isopi, V. Capalbo, A. D. Hincks +27
According to CMB measurements, baryonic matter constitutes about of the mass-energy density of the universe. A significant population of these baryons, for a long time referr…
