From the abstract: "This paper focuses on cosmological
constraints derived from analysis of WMAP data alone. A simple
Lambda CDM cosmological model fits the five-year WMAP temperature
and polarization data. The basic parameters of the model are consistent
with the three-year data and now better constrained…. With five
years of polarization data, we have measured the optical depth to
reionization, tau > 0, at 5 sigma significance. The redshift of an
instantaneous reionization is constrained to be z(reion) = 11.0 +/- 1.4
with 68% confidence. The 2 sigma lower limit is z(reion) > 8.2, and the
3 sigma limit is z(reion) > 6.7. This excludes a sudden reionization of
the universe at z = 6 at more than 3.5 sigma significance, suggesting that
reionization was an extended process. Using two methods for polarized
foreground cleaning we get consistent estimates for the optical depth,
indicating an error due to the foreground treatment of tau similar to 0.01.
This cosmological model also fits small-scale cosmic microwave background
(CMB) data, and a range of astronomical data measuring the expansion rate
and clustering of matter in the universe…."
