Dianoga simulations of galaxy clusters and groups: Properties of the baryonic components
Stefano Borgani, Alice Damiano, Elena Rasia +12
We introduce the Dianoga set of cosmological simulations of galaxy clusters and groups, specifically aimed at studying the impact of the implementation of AGN feedback and star for…
Probing the baryonic--dark matter connection in galaxy clusters using X-rays with gated recurrent unit neural networks
Asif Iqbal, Subhabrata Majumdar, Weiguang Cui +3
Accurate cluster mass measurements are crucial for cosmology, yet conventional hydrostatic equilibrium (HSE) methods can suffer from systematic biases, particularly in dynamically…
The Three Hundred project: Low Gas Fraction Galaxy Clusters properties and their environment
Francesco Guidi, Marco De Petris, Sara Santoni +7
Galaxy cluster samples based on X-ray and Sunyaev-Zel'dovich (SZ) observations are affected by selection biases. These catalogs preferentially include systems with high gas content…
The Three Hundred Project: Validating inference from mock X-ray and millimetre analyses of galaxy clusters
F. De Luca, H. Bourdin, P. Mazzotta +6
Measurements of thermodynamical quantities in galaxy clusters are differently affected by simplified modelling of radially averaged observables in the X-ray and millimetre bands. T…
CHEX-MATE: AMALGAM weak-lensing analysis of 41 Planck Sunyaev-Zel'dovich-selected galaxy clusters
Keiichi Umetsu, Raphael Gavazzi, Mauro Sereno +20
We present a weak-lensing shear analysis of 41 Planck SZ-selected galaxy clusters at from the CHEX-MATE sample, using wide-field Subaru/Suprime-Cam and CFHT/Meg…
CHEX-MATE: Are we getting cluster thermodynamics right?
R. Seppi, D. Eckert, E. Rasia +19
Galaxy clusters offer powerful insights into the large-scale structure of the Universe and the physics of baryons in hot state. Their scientific exploitation, however, hinges on ou…
