Abstract

Context.Some previous investigations have found that the fraction (fAGN) of active galactic nuclei (AGNs) is lower in clusters than in the field. This can result from the suppression of galaxy–galaxy mergers in high-velocity dispersion () clusters, if the formation and/or fueling of AGNs is directly related to the merging process.
