Number of mergers experienced by supermassive galaxies for $\lambda /\sqrt{\varepsilon }=0.31$ (left panel) and 0.71 (right panel). Solid and dashed blue lines show the number of all and only gas-rich mergers experienced by disks. In contrast, dash-dotted and dotted red lines correspond to all and only gas-rich mergers experienced by our CS, respectively. Up to 45% of disks in our sample did not experience any merger at z<1, with fewer than 20% of disks in our sample experiencing two or more mergers. On the other hand, spheroidal galaxies have a very active merging history, with more than 70% of them experiencing one or two mergers at z<1.
