Four selected disturbed galaxy clusters at redshift z = 0.1; the top ones are clusters in the early interacting stages, while the bottom panels show clusters in more advanced interacting stages where the secondary structure has already crossed R₂₀₀ of the main one. On the left side, the projected gas mass distribution for redshift z = 0.1. On the right side, we have the temporal evolution of total virial mass M₂₀₀ and the sSFR of their satellite galaxies. The clusters exhibit a short boost followed by a decrease in the sSFR, indicating that the sSFR's dynamical state may be influenced by the cluster's dynamical state.
