[124.01] Contraining the Local Galaxy Cluster Abundance with HIFLUGCS

T.H. Reiprich, H. Böhringer, P. Schuecker (Max-Planck-Institut)

A new complete X-ray flux-limited sample of galaxy clusters (HIFLUGCS) has been compiled based on the ROSAT All-Sky Survey. The clusters have been reanalysed in detail using mainly ROSAT PSPC pointed observations. The empirical X-ray luminosity -- gravitational mass relation and its scatter is quantified. The observed local gravitational mass function is determined and compared to analytical mass functions. The results are consistent with an open Cold Dark Matter universe. It is found that most of the mass in the Universe resides outside galaxy clusters.
