Dependency of halo concentration on mass, redshift and fossilness in Magneticum hydrodynamic simulations
Antonio Ragagnin, Klaus Dolag, Lauro Moscardini +2
We study the dependency of the concentration on mass and redshift using three large N-body cosmological hydrodynamic simulations carried out by the Magneticum project. We constrain…
Athena X-IFU synthetic observations of galaxy clusters to probe the chemical enrichment of the Universe
E. Cucchetti, E. Pointecouteau, P. Peille +14
Answers to the metal production of the Universe can be found in galaxy clusters, notably within their Intra-Cluster Medium (ICM). The X-ray Integral Field Unit (X-IFU) on board the…
On the relative bias of void tracers in the Dark Energy Survey
G. Pollina, N. Hamaus, K. Paech +61
Luminous tracers of large-scale structure are not entirely representative of the distribution of mass in our Universe. As they arise from the highest peaks in the matter density fi…
Evolution of the degree of substructures in simulated galaxy clusters
Cristiano De Boni, Hans Böhringer, Gayoung Chon +1
We study the evolution of substructure in the mass distribution with mass, redshift and radius in a sample of simulated galaxy clusters. The sample, containing objects, span…
AGN contamination of galaxy-cluster thermal X-ray emission: predictions for eRosita from cosmological simulations
V. Biffi, K. Dolag, A. Merloni
In this study, we present a modelling of the X-ray emission from the simulated SMBHs within the cosmological hydrodynamical Magneticum Pathfinder Simulation, in order to study the…
