T1 Distribution of baryonic and non-baryonic matter in clusters of galaxies

AB We present the analysis of baryonic and non-baryonic matter distributions in a sample of eleven nearby clusters (0.03 < z < 0.09) with temperatures between 4.4 and 9.4 keV. These galaxy clusters have been studied in detail using X-ray data and global physical properties have been determined. Correlations between these quantities have been analysed and compared with the results for distant clusters. We found an interesting dependence between the relative gas extent (expressed as the ratio of gas mass fractions at r(500) and 0.5 x r(500)) and the total cluster mass. The extent of the gas relative to the extent of the dark matter tends to be larger in less massive clusters. This dependence might give us some hints about non-gravitational processes in clusters.
