Cumulative and differential distributions of the number of merger events as a function of redshift. Cl13, D9, and CosmoBox are in the first, second, and third rows, respectively. The REPOS simulation results are marked with a dash-dotted red line (with a shaded area marking the differential distributions), the DYNFRIC simulations with a blue solid line and the DYNMASS simulations with a dashed green line. The curves stop at the redshift corresponding to the occurrence of last merger event.
