Omegam - Different Ways to Determine the Matter Density of the Universe
Abstract
A summary of various measurements of the mean matter density in the universe, Omegam, 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 Omegam values around 0.3, but there are also some measurements that favour a higher or a smaller value.
