PPT-Clusters of galaxies

With a widefield multiIFU spectrograph Cluster studies Clusters provide large samples of galaxies in a moderate field Unique perspective on the interaction of galaxies with their environment As they operate much as a closed box they are useful as tracers of galaxy evolution and of cosmology. .
