Simulating the formation of a proto-cluster at z~2
A. Saro, S. Borgani, L. Tornatore +3
We present results from two high-resolution hydrodynamical simulations of proto-cluster regions at z~2.1. The simulations have been compared to observational results for the socall…
Evolution of the metal content of the intra-cluster medium with hydrodynamical simulations
D. Fabjan, L. Tornatore, S. Borgani +2
We present a comparison between simulation results and X-ray observational data on the evolution of the metallicity of the intra-cluster medium (ICM). The simulations of galaxy clu…
On the Dynamical Origin of the ICM Metallicity Evolution
S. A. Cora, L. Tornatore, P. Tozzi +1
We present a study on the origin of the metallicity evolution of the intra-cluster medium (ICM) by applying a semi-analytic model of galaxy formation to N-body/SPH (smoothed partic…
The chemical enrichment of the ICM from hydrodynamical simulations
S. Borgani, D. Fabjan, L. Tornatore +3
The study of the metal enrichment of the intra-cluster and inter-galactic media (ICM and IGM) represents a direct means to reconstruct the past history of star formation, the role…
Population III stars: hidden or disappeared ?
L. Tornatore, A. Ferrara, R. Schneider
A PopIII/Pop II transition from massive to normal stars is predicted to occur when the metallicity of the star forming gas crosses the critical range Z_cr = 10^(-5 +/- 1) Z_sun. To…
X-MAS2: Study Systematics on the ICM Metallicity Measurements
E. Rasia, P. Mazzotta, H. Bourdin +5
(Abridged)The X-ray measurements of the ICM metallicity are becoming more frequent due to the availability of powerful X-ray telescope with excellent spatial and spectral resolutio…
Metal and molecule cooling in simulations of structure formation
U. Maio, K. Dolag, B. Ciardi +1
Cooling is the main process leading to the condensation of gas in the dark matter potential wells and consequently to star and structure formation. In a metal-free environment, the…
Chemical enrichment of galaxy clusters from hydrodynamical simulations
L. Tornatore, S. Borgani, K. Dolag +1
We present cosmological hydrodynamical simulations of galaxy clusters aimed at studying the process of metal enrichment of the intra--cluster medium (ICM). These simulations have b…
Metal and molecule cooling in simulations of structure formation
U. Maio, K. Dolag, B. Ciardi +1
This submission has been withdrawn by arXiv administrators because it is a duplicate of 0704.2182.
Properties of the galaxy population in hydrodynamical simulations of clusters
A. Saro, S. Borgani, L. Tornatore +5
We present a study of the galaxy population predicted by hydrodynamical simulations for a set of 19 galaxy clusters based on the GADGET-2 Tree+SPH code. These simulations include g…
Hot and Cooled baryons in SPH simulations of galaxy clusters: physics and numerics
S. Borgani, K. Dolag, G. Murante +7
We discuss an extended set of Tree+SPH simulations of galaxy clusters, with the goal of investigating the interplay between numerical resolution effects and star-formation/feedback…
Simulating the Soft X-ray excess in clusters of galaxies
L. -M. Cheng, S. Borgani, P. Tozzi +7
The detection of excess of soft X-ray or Extreme Ultraviolet (EUV) radiation, above the thermal contribution from the hot intracluster medium (ICM), has been a controversial subjec…
