Simulation view of galaxy clusters with low X-ray surface brightness
Antonio Ragagnin, Stefano Andreon, Emanuella Puddu
X-ray selected samples are known to miss galaxy clusters that are gas poor and have a low surface brightness. This is different for the optically selected samples such as the X-ray…
Euclid preparation. XXIV. Calibration of the halo mass function in CDM cosmologies
Euclid Collaboration, T. Castro, A. Fumagalli +179
Euclid's photometric galaxy cluster survey has the potential to be a very competitive cosmological probe. The main cosmological probe with observations of clusters is their number…
Impact of H-driven star formation and stellar feedback from low-enrichment environments on the formation of spiral galaxies
Milena Valentini, Klaus Dolag, Stefano Borgani +8
The reservoir of molecular gas (H) represents the fuel for the star formation (SF) of a galaxy. Connecting the star formation rate (SFR) to the available H is k…
Mapping "out-of-the-box" the properties of the baryons in massive halos
M. Angelinelli, S. Ettori, K. Dolag +2
We study the distributions of the baryons in massive halos () in the suite of Smoothed Particle Hydrodynamical cosmological simula…
Cosmological simulations with rare and frequent dark matter self-interactions
Moritz S. Fischer, Marcus Brüggen, Kai Schmidt-Hoberg +4
Dark matter (DM) with self-interactions is a promising solution for the small-scale problems of the standard cosmological model. Here we perform the first cosmological simulation o…
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…
The BEHOMO project: LTB -body simulations
V. Marra, T. Castro, D. Camarena +2
Our Universe may feature large-scale inhomogeneities and anisotropies which cannot be explained by the standard model of cosmology, that is, the homogeneous and isotropic FLRW metr…
