Abstract: We investigate galaxy mergers in the A901/902 supercluster at z ∼ 0.165, based on HST ACS F606W, COMBO-17, Spitzer 24 μm, XMM-Newton X-ray, and gravitational lensing maps, as part of the STAGES survey. We utilize two methods to identify interacting galaxies in A901/902: visual classification and quantitative CAS parameters. In this article, we summarize our results for the frequency, distribution, color, and star formation rates of mergers, compared to non-interacting galaxies in A901/902. We also compare our results to other studies of clusters and groups, as well as theoretical predictions.
