Room 208 (Hynes Convention Center)
The Wilkinson Microwave Anisotropy Probe (WMAP) has completed nine full years of mapping the CMB in five frequency bands. With these data the team has charted the power spectrum down to the cosmic variance limit to beyond l=500 and the first three acoustic peaks are accurately measured. From the temperature and polarization spectra, the parameters of the standard LCDM model are deduced. Through including external data sets, extensions to the standard model are tested. These extensions include the properties of neutrinos, constraints on dark energy, etc. In this talk the most recent results from WMAP are presented.
