Normalised distributions of AGN fraction in mergers (orange) and non-mergers (blue), as a function of redshift (z-bin 1: left; z-bin 2: middle; z-bin 3: right) and AGN type (SED AGN: top; MIR AGN: bottom). In each panel, we show the results of a KS test, where D is the test result and p is the corresponding p−value. For SED AGNs, the f_AGN distribution in mergers is considerably different from that in non-mergers in all z-bins. MIR AGNs have different merger and non-merger distributions at z ≥ 0.31.
