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…
The Dark Side and its Nature
S. A. Bonometto, R. Mainini, L. P. L. Colombo
Although the cosmic concordance cosmology is quite successful in fitting data, fine tuning and coincidence problems apparently weaken it. We review several possibilities to ease it…
Mass functions in coupled Dark Energy models
Roberto Mainini, Silvio Bonometto
We evaluate the mass function of virialized halos, by using Press & Schechter (PS) and/or Steth & Tormen (ST) expressions, for cosmologies where Dark Energy (DE) is due to a scalar…
