Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology
A. E. Evrard, J. Bialek, M. Busha +14
We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result i…
Spectroscopic-Like Temperature of Clusters of Galaxies and Cosmological Implications
P. Mazzotta, E. Rasia, S. Borgani +3
The thermal properties of hydrodynamical simulations of galaxy clusters are usually compared to observations by relying on the emission-weighted temperature T_ew, instead of on the…
Arc statistics with realistic cluster models
Massimo Meneghetti, Matthias Bartelmann, Lauro Moscardini +3
Arc statistics is known to be a powerful cosmological tool. Numerical lensing simulations show that orders of magnitude differences in the number of {\em giant} arcs on the whole s…
Cluster galaxies: contribution to the arc statistics
Massimo Meneghetti, Micol Bolzonella, Matthias Bartelmann +2
We present the results of a set of numerical simulations aiming at evaluating the effects of cluster galaxies on the arc statistics. At this goal we use nine different galaxy clust…
Hydrodynamic Simulations of Galaxy Formation
Giuseppe Tormen
This review is a short introduction to numerical hydrodynamics in a cosmological context, intended for the non specialist. The main processes relevant to galaxy formation are first…
The Structure of Dark Matter Halos
Giuseppe Tormen
I use -body simulations to investigate the morphology and the dynamical evolution and properties of dark matter halos in clusters of galaxies. My sample consists of nine massive…
