We present a study of galaxies in the STAGES survey of the Abell 901/902
supercluster at z˜0.165, based on HST/ACS F606W, COMBO-17, Spitzer
24 μm, XMM-Newton X-ray, and gravitational lensing maps. We
characterize galaxies with strong, externally-triggered morphological
distortions and normal, relatively undisturbed galaxies, using visual
classification and quantitative CAS parameters. We compare normal and
distorted galaxies in terms of their frequency, distribution within the
cluster, star formation properties, and relationship to dark matter or
surface mass density, and intra-cluster medium density. We report here
our preliminary results.
