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…
Galaxies in the central regions of simulated galaxy clusters
Antonio Ragagnin, Massimo Meneghetti, Luigi Bassini +20
In this paper, we assess the impact of numerical resolution and of the implementation of energy input from AGN feedback models on the inner structure of cluster sub-haloes in hydro…
The probability of galaxy-galaxy strong lensing events in hydrodynamical simulations of galaxy clusters
Massimo Meneghetti, Antonio Ragagnin, Stefano Borgani +27
Meneghetti et al. (2020) recently reported an excess of galaxy-galaxy strong lensing (GGSL) in galaxy clusters compared to expectations from the LCDM cosmological model. Theoretica…
Exploring the role of cosmological shock waves in the Dianoga simulations of galaxy clusters
Susana Planelles, Stefano Borgani, Vicent Quilis +6
Cosmological shock waves are ubiquitous to cosmic structure formation and evolution. As a consequence, they play a major role in the energy distribution and thermalization of the i…
Halo cluster shapes: Insights from simulated galaxies and ICL with prospects for weak lensing applications
Elizabeth J. Gonzalez, Cinthia Ragone-Figueroa, Carlos J. Donzelli +3
We present a detailed study of the shapes and alignments of different galaxy cluster components using hydrodynamical simulations. We compute shape parameters from the Dark Matter (…
Pressure of the hot gas in simulations of galaxy clusters
S. Planelles, D. Fabjan, S. Borgani +11
We analyze the radial pressure profiles, the ICM clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in…
