From the abstract: "The Wilkinson Microwave Anisotropy
Probe (WMAP) 5-year data provide stringent limits on
deviations from the minimal, six-parameter. cold dark matter model. We
report these limits and use them to constrain the physics of cosmic
inflation via Gaussianity, adiabaticity, the power spectrum of primordial
fluctuations, gravitational waves, and spatial curvature. We also constrain
models of dark energy via its equation of state, parity-violating
interaction, and neutrino properties, such as mass and the number of
species. We detect no convincing deviations from the minimal model....We
obtain tight, simultaneous limits on the (constant) equation of state of
dark energy and the spatial curvature of the universe: -0.14 < 1 + w(0)
< 0.12 (95% CL) and -0.0179 < Omega(k) < 0.0081 (95% CL). We
provide a set of "WMAP distance priors," to test a variety of dark
energy models with spatial curvature. We test a time-dependent w with a
present value constrained as -0.33 < 1 + w(0) < 0.21 (95% CL).
Temperature and dark matter fluctuations are found to obey the adiabatic
relation to within 8.9% and 2.1% for the axion-type and curvaton-type dark
matter, respectively....Finally, quantitative limits on
physically-motivated primordial non-Gaussianity parameters are -9 <
f(NL)(local) < 111 (95% CL) and -151 < f(NL)(equil) < 253 (95% CL)
for the local and equilateral models, respectively."
