"Three-year Wilkinson Microwave Anisotropy Probe (WMAP) observations: Implications for cosmology," by D.N. Spergel and 21 others, Astrophysical Journal Supplement Series, 170(2): 377-408, June 2007.

From the Abstract: "A simple cosmological model with only six parameters (matter density, Omega(m)h(2), baryon density, Omega(b)h(2), Hubble constant, H-0, amplitude of fluctuations, sigma(8), optical depth, tau, and a slope for the scalar perturbation spectrum, n(s)) fits not only the 3 year WMAP temperature and polarization data, but also small-scale CMB data, light element abundances, large-scale structure observations, and the supernova luminosity/distance relationship. Using WMAP data only, the best-fit values for cosmological parameters for the power-law flat Lambda cold dark matter (Lambda CDM) model are (Omega(m)h(2), Omega(b)h(2), h, n(s), tau, sigma(s)) = (0.1277(-0.0079)(+0.0080),
0.02229 +/- 0.00073, 0.732(-0.032)(+0.031), 0.958 +/- 0.016,0.089 +/- 0.030, 0.761(-0.048)(+0.049)). The 3 year data dramatically shrink the allowed volume in this six-dimensional parameter space. Assuming that the primordial fluctuations are adiabatic with a power-law spectrum, the WMAP data alone require dark matter and favor a spectral index that is significantly less than the Harrison-Zel'dovich-Peebles scale-invariant spectrum ( n(s) = 1, r = 0). Adding additional data sets improves the constraints on these components and the spectral slope.....For a flat universe, the combination of WMAP and other astronomical data yield a constraint on the sum of the neutrino masses, Sigma m(nu) < 0.66 eV (95%CL). Consistent with the predictions of simple inflationary theories, we detect no significant deviations from Gaussianity in the CMB maps using Minkowski functionals, the bispectrum, trispectrum, and a new statistic designed to detect large-scale anisotropies in the fluctuations."
