Cosmological implications of the first year Wilkinson Microwave Anisotropy Probe results

The Wilkinson Microwave Anisotropy Probe (WMAP) team has recently analyzed and released the first-year data. We will review the implications for cosmology of these results. The highlight is that cosmology now has a standard cosmological model. With only 6 parameters the model fits not only WMAP data remarkably well, but also a host of other astronomical observations. We also present the results on neutrino mass limits and on dark energy properties from a joint likelihood analysis of WMAP data with small-scale CMB experiments and large-scale structure surveys. The data and supplementary information are publicly available and can be found on the experiment web site at http://lambda.gsfc.nasa.gov.
