The youth of the intracluster medium. I. A non-parametric characterisation of the gas and electron number density profiles of protoclusters
David Vallés-Pérez, Annalisa Bonafede, Klaus Dolag +3
Context. Protoclusters of galaxies are the earliest phase in the assembly of galaxy clusters and can provide invaluable information about plasma physics, cosmic magnetism, and cosm…
The eventful life journey of galaxy clusters. II. Impact of mass accretion on the thermodynamical structure of the ICM
David Vallés-Pérez, Susana Planelles, Vicent Quilis
Context. The internal structure of the intracluster medium (ICM) is tightly linked to the assembly history and physical processes in groups and clusters, but the role of recent acc…
The signature of major mergers on the hydrostatic mass bias of galaxy clusters
Isac Barranco-Llorca, David Vallés-Pérez, Susana Planelles +1
While galaxy cluster masses are fundamental cosmological observables, estimates based on intra-cluster medium observations rely on hydrostatic equilibrium, introducing a systematic…
AVISM: Algorithm for Void Identification in coSMology
Ãscar Monllor-Berbegal, David Vallés-Pérez, Susana Planelles +1
Cosmic voids are key elements in our understanding of the large-scale structure of the Universe. They are crucial to constrain cosmological parameters, understand the structure for…
The eventful life journey of galaxy clusters. I. Impact of DM halo and ICM properties on their full assembly histories
David Vallés-Pérez, Susana Planelles, Vicent Quilis
Context. Galaxy clusters assemble over gigayears in a very anisotropic environment, which causes a remarkable diversity in their mass assembly histories (MAH). Aims. In this work,…
Turbulent Pressure Support in Galaxy Clusters -- Impact of the Hydrodynamical Solver
Frederick Groth, Milena Valentini, Ulrich P. Steinwandel +2
The amount of turbulent pressure in galaxy clusters is still debated, especially as for the impact of the dynamical state and the hydro-method used for simulations. We study the tu…
