Dark Matter and Dark Energy from a single scalar field
Roberto Mainini, Loris Colombo, Silvio A. Bonometto
The strong CP problem was solved by Peccei & Quinn by introducing axions, which are a viable candidate for DM. Here the PQ approach is modified so to yield also Dark Energy (DE), w…
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…
