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…
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…
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…
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…
Galaxy cluster count cosmology with simulation-based inference
M. Regamey, D. Eckert, R. Seppi +4
The abundance and mass distribution of galaxy clusters is a sensitive probe of cosmological parameters, through the sensitivity of the high-mass end of the halo mass function to $Ω…
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: Multi-probe analysis of Abell 1689
L. Chappuis, D. Eckert, M. Sereno +25
The nature of the elusive dark matter can be probed by comparing the predictions of the cold dark matter framework with the gravitational field of massive galaxy clusters. However,…
Double radio relics and radio halo in the high redshift galaxy cluster El Gordo with the Upgraded GMRT
R. Kale, A. Botteon, D. Eckert +5
Diffuse synchrotron radio sources associated with the intra-cluster medium of galaxy clusters are of special interest at high redshifts to understand the magnetization and particle…
