Cosmology with sterile neutrino masses from oscillation experiments
Jostein R. Kristiansen, Øystein Elgarøy, Carlo Giunti +1
There are hints, both from cosmology and from neutrino oscillation experiments, that one or two sterile neutrinos with eV masses are favored. We consider the implications of combin…
Reactor sterile neutrinos, dark energy and the age of the universe
Jostein R. Kristiansen, Oystein Elgaroy
There are indications that the neutrino oscillation data from reactor experiments and the LSND and MiniBooNE experiments show a preference for two sterile neutrino species, both wi…
Do WMAP5 data favor neutrino mass and a coupling between Cold Dark Matter and Dark Energy?
S. A. Bonometto, G. La Vacca, J. R. Kristiansen +2
We fit WMAP5 and related data by allowing for a CDM--DE coupling and non--zero neutrino masses, simultaneously. We find a significant correlation between these parameters, so that…
Dynamical Dark Energy model parameters with or without massive neutrinos
G. La Vacca, J. R. Kristiansen
We use WMAP5 and other cosmological data to constrain model parameters in quintessence cosmologies, focusing also on their shift when we allow for non-vanishing neutrino masses. Th…
Do 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
We allow simultaneously for a CDM--DE coupling and non--zero neutrino masses and find that significant coupling and neutrino mass are (slightly) statistically favoured in respect t…
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…
