Do WMAP data favor neutrino mass and a coupling between Cold Dark Matter and Dark Energy?
G. La Vacca, J. R. Kristiansen, L. P. L. Colombo +2
Within the frame of cosmologies where Dark Energy (DE) is a self--interacting scalar field, we allow for a CDM--DE coupling and non--zero neutrino masses, simultaneously. In their…
Nature of Dark Energy and Polarization Measurements
R. Mainini, L. P. L. Colombo, S. A. Bonometto
High sensitivity polarization measures, on wide angular scales, together with data on anisotropy, can be used to fix DE parameters. In this paper, first of all, we aim to determine…
The STRIP instrument of the Large Scale Polarization Explorer: microwave eyes to map the Galactic polarized foregrounds
C. Franceschet, S. Realini, A. Mennella +48
In this paper we discuss the latest developments of the STRIP instrument of the "Large Scale Polarization Explorer" (LSPE) experiment. LSPE is a novel project that combines ground-…
Structure Formation in Dynamical Dark Energy Models
A. V. Maccio', S. A. Bonometto, R. Mainini +1
We perform N-body simulations for models with a DE component. Besides of DE with constant negative state parameter w, we consider DE due to scalar fields, self-interacting through…
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…
Cosmic Microwave Background Polarization and reionization: constraining models with a double reionization
L. P. L. Colombo, G. Bernardi, L. Casarini +4
Neutral hydrogen around high-z QSO and an optical depth tau ~ 0.17 can be reconciled if reionization is more complex than a single transition at z ~ 6-8. Tracing its details could…
