[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, Ω^sub 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 Ω^sub m^ values around 0....

Zusammenfassung:A summary of various measurements of the mean matter density in the universe, Ω^sub 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 Ω^sub m^ values around 0.3, but there are also some measurements that favour a higher or a smaller value.[PUBLICATION ABSTRACT]
