Distributions of the visual Interaction Metric (IM) for AGNs and inactive control galaxies. Panels left to right span three distinct bins in redshift. 1000 draws of a mass-matched control sample are analyzed to determine the 1σ/2σ scatter in the IM distributions for inactive galaxies, shown as dark/light grey zones in the histograms. Red open histograms show the parameter distributions for the AGNs. Interacting and merging systems are a minor fraction of galaxies and AGNs at all redshifts. AGNs are generally equally likely to be in an interacting host as inactive galaxies, though a small excess of AGNs in mergers may be discernible at low redshifts.
