The impact of cluster mergers on arc statistics
Elena Torri, Massimo Meneghetti, Matthias Bartelmann +3
We study the impact of merger events on the strong lensing properties of galaxy clusters. Previous lensing simulations were not able to resolve dynamical time scales of cluster len…
X-ray properties of galaxy clusters and groups from a cosmological hydrodynamical simulation
S. Borgani, G. Murante, V. Springel +6
We present results on the X-ray properties of clusters and groups of galaxies, extracted from a large hydrodynamical simulation. We used the GADGET code to simulate a LambdaCDM mod…
Numerical study of halo concentrations in dark-energy cosmologies
Klaus Dolag, Matthias Bartelmann, Francesca Perrotta +4
We study the concentration parameters, their mass dependence and redshift evolution, of dark-matter halos in different dark-energy cosmologies with constant and time-variable equat…
A dynamical model for the distribution of dark matter and gas in galaxy clusters
Elena Rasia, Giuseppe Tormen, Lauro Moscardini
Using high-resolution non-radiative hydrodynamic simulations of galaxy clusters we obtain simple analytic formulae for DM and gas distribution in the spherical approximation. We de…
Constraints on extended quintessence from high-redshift Supernovae
Paolo Caresia, Sabino Matarrese, Lauro Moscardini
We obtain constraints on quintessence models from magnitude-redshift measurements of 176 type Ia Supernovae. The considered quintessence models are ordinary quintessence, with Ratr…
High-Resolution Simulations of Cosmic Microwave Background non-Gaussian Maps in Spherical Coordinates
Michele Liguori, Sabino Matarrese, Lauro Moscardini
We describe a new numerical algorithm to obtain high-resolution simulated maps of the Cosmic Microwave Background (CMB), for a broad class of non-Gaussian models. The kind of non-G…
