英文摘要	In the present paper, we studied the correlations among different quantities in the clusters of galaxies observed by Newman et al. We found an anti-correlation among the slope , the effective radius, R-e, and a correlation among the core radius r(core) and R-e. Moreover, the mass in 100 kpc (mainly dark matter) is correlated with the mass inside 5 kpc (mainly baryons). The previous correlations can be understood in a two phase formation model: a first dissipative phase forming the proto-BCG and a second dissipationless phase, in which the inner density profile is flattened by the interaction of baryonic clumps and the DMhalo through dynamical friction (DF).
