The Shapley super-cluster as seen in the Planck survey. Upper panel: reconstructed thermal SZ map 3.2° × 1.8° from MILCA (Hurier et al. 2013). The dotted circles represent apertures of θ₅₀₀ from the MCXC meta-catalogue around the resolved clusters. Lower panel: composite view of the optical from DSS images (white), X-rays from ROSAT (pink) survey and of the thermal SZ effect as seen in Planck (blue).
