Shapley Supercluster Survey: observing transformations of galaxies in a stormy environment
The multi-wavelength survey of the Shapley supercluster (z~0.05) covers a contiguous area of 260 square Mpc centred on the supercluster core including 11 clusters showing evidence of cluster-cluster interactions. Optical (ugri) and near-infrared (K) imaging acquired with VST and VISTA allow us to study the galaxy population down to m*+6 at the supercluster redshift. A dedicated spectroscopic survey with AAOmega on the Anglo-Australian Telescope provides a magnitude-limited sample of supercluster members with 80% completeness at ~m*+3. I will present the main results of this project.
