Maps of thermal and kinetic SZ effect from the Hubble volume simulation (left column), from the local universe (middle column), and total thermal and kinetic SZ effects from both simulations together, smoothed here to a sky resolution of 5 arc-min (right column). All the displayed maps are small 5° × 5° patches centred on the North Galactic Pole. The original full sky maps are at HEALPix N_side = 2048 for the Hubble volume, and at N_side = 1024 for the local hydrodynamical simulations. The contribution from the local universe comprises a large cluster at sky coordinates close to those of the Coma cluster, which dominates the total SZ emission in the maps displayed here.
