Cosmologies with dynamical and coupled Dark Energy vs. CMB data
Silvio A. Bonometto, Luciano Casarini, Loris P. L. Colombo +1
We compare a large set of cosmologies with WMAP data, performing a fit based on a MCMC algorithm. Besides of LCDM models, we take dynamical DE models, where DE and DM are uncoupled…
The Nature of Dark Energy from deep Cluster Abundance
P. Solevi, R. Mainini, S. A. Bonometto
We show that using the redshift dependence of the deep cluster abundance to detect the nature of Dark Energy is a serious challenge. We compare the expected differences between fla…
Polarization Measures And Nature Of Dark Energy
L. P. L. Colombo, R. Mainini, S. A. Bonometto
Polarization measures, on wide angular scales, together with anisotropy data, can fix DE parameters. Here we discuss the sensitivity needed to provide significant limits. Our analy…
Morphological evolution of X-ray clusters using hydrodynamical simulations
R. Valdarnini, S. Ghizzardi, S. Bonometto
A large set of TREESPH simulations is used to test the global morphology of galaxy clusters and its evolution against X-ray data. A powerful method to investigate substructures in…
Deviations from Hierarchical Clustering in Real and Redshift Space
S. Ghigna, S. A. Bonometto, L. Guzzo +4
We discuss the effects of redshift--space distortions on the estimate of high order galaxy correlation functions. We use both the Perseus--Pisces redshift survey and the results of…
