"WMAP Five-Year Results"
I will present new results from five years of WMAP observations. The
WMAP satellite measures the Cosmic Microwave Background temperature and
polarization anisotropy over the whole sky. With five years of data, we
detect no significant deviations from the simple LCDM cosmological
model: a flat universe filled with baryons, photons, cold dark matter,
neutrinos, and a cosmological constant. I will describe the
observations, and discuss the cosmological implications for cosmic
inflation, for the reionization of the universe by the first stars, and
for the contents of the universe including neutrinos and dark energy.
