Omega-m - Different ways to determine the matter density of the universe

A summary of various measurements of the mean matter density in the universe, Omega-m, is presented. Results from very different kinds of methods using various astronomical objects - from supernovae to large-scale structure - are shown. There is a remarkable preference for Omega-m values around 0.3,...

Zusammenfassung:A summary of various measurements of the mean matter density in the universe, Omega-m, is presented. Results from very different kinds of methods using various astronomical objects - from supernovae to large-scale structure - are shown. There is a remarkable preference for Omega-m values around 0.3, but there are also some measurements that favor a higher or a smaller value. (Author)
