Abstract:
Recently the WMAP satellite has provided new data on the cosmic
microwave background (CMB) with an unprecedented accuracy. Apart from
yielding detailed information about cosmological parameters such as the
matter density and the cosmological constant, this data also has direct
applications to particle physics. The prime example is the study of
neutrino properties using CMB data in conjunction with other
cosmological data. In the talk I will review the current observational
situation in cosmology, as well as the status of cosmological parameter
estimation and its implications for particle physics.
