Growth and dissolution of spherical density enhancements in SCDEW cosmologies
Silvio A. Bonometto, Roberto Mainini
Strongly Coupled Dark Energy plus Warm dark matter (SCDEW) cosmologies are based on the finding of a conformally invariant (CI) attractor solution during the early radiative expans…
Dark Matter & Dark Energy from a single scalar field: CMB spectrum and matter transfer function
Mainini Roberto, Silvio Bonometto
The dual axion model (DAM), yielding bot DM and DE form a PQ-like scalar field solving the strong CP problem, is known to allow a fair fit of CMB data. Recently, however, it was sh…
Dark Matter, Dark Energy and the solution of the strong CP problem
Roberto Mainini, Loris Colombo, Silvio Bonometto
The strong CP problem was solved by Peccei & Quinn by introducing axions, a viable candidate for Dark Matter (DM). Here the PQ approach is modified so to yield also Dark Energy (DE…
Cosmic opacity to CMB photons and polarization measurements
L. P. L. Colombo, S. A. Bonometto
Anisotropy data analysis leaves a significant degeneracy between primeval spectral index (n_s) and cosmic opacity to CMB photons (τ). Low--l polarization measures, in principle, ca…
Cluster Correlation in Mixed Models
A. Gardini, S. A. Bonometto, G. Murante +1
We evaluate the dependence of the cluster correlation length r_c on the mean intercluster separation D_c, for three models with critical matter density, vanishing vacuum energy (La…
Global cluster morphology and its evolution: X-ray data vs CDM, LCDM and mixed models
R. Valdarnini, S. Ghizzardi, S. A. Bonometto
The global structure of galaxy clusters and its evolution are tested within a large set of TREESPH simulations, so to allow a fair statistical comparison with available X-ray data.…
