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…

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…
