Modeling active galactic nuclei: ongoing problems for the faint-end of the luminosity function
F. Marulli, E. Branchini, L. Moscardini +1
We consider simple semi-analytic models that relate the active galactic nuclei (AGN) evolution to the merging history of their host dark matter haloes and quantify their ability of…
Simulated X-ray galaxy clusters at the virial radius: slopes of the gas density, temperature and surface brightness profiles
M. Roncarelli, S. Ettori, K. Dolag +3
Using a set of hydrodynamical simulations of 9 galaxy clusters with masses in the range 1.5 10^{14} M_sun < M_vir < 3.4 10^{15} M_sun, we have studied the density, temperature and…
Searching dark-matter halos in the GaBoDS survey
M. Maturi, M. Schirmer, M. Meneghetti +2
We apply the linear filter for the weak-lensing signal of dark-matter halos developed in Maturi et al. (2005) to the cosmic-shear data extracted from the Garching-Bonn-Deep-Survey…
Early structure formation in quintessence models and its implications for cosmic reionisation from first stars
U. Maio, K. Dolag, M. Meneghetti +5
We present the first hydrodynamic N-body simulations of primordial gas clouds responsible for the reionisation process in dark energy cosmologies. We compare the cosmological const…
Arc sensitivity to cluster ellipticity, asymmetries and substructures
Massimo Meneghetti, Rodolfo Argazzi, Francesco Pace +5
We investigate how ellipticity, asymmetries and substructures separately affect the ability of galaxy clusters to produce strong lensing events, i.e. gravitational arcs, and how th…
The Clustering Evolution of Distant Red Galaxies in the GOODS-MUSIC Sample
A. Grazian, A. Fontana, L. Moscardini +8
We use the GOODS-MUSIC sample, a catalog of ~3000 Ks-selected galaxies based on VLT and HST observation of the GOODS-South field with extended multi-wavelength coverage (from 0.3 t…
