Abstract (from CDS):
By combining WMAP data with other astronomical data, we constrain the geometry of the universe, Ωtot=1.02±0.02, and the equation of state of the dark energy, w←0.78 (95% confidence limit assuming w≥-1). The combination of WMAP and 2dFGRS data constrains the energy density in stable neutrinos: Ωνh2<0.0072 (95% confidence limit). For three degenerate neutrino species, this limit implies that their mass is less than 0.23 eV (95% confidence limit). The WMAP detection of early reionization rules out warm dark matter.
