SLOW in different wavebands. From top to bottom: distribution of stellar mass in SLOW, X-ray surface brightness, and Compton-Y. A much larger dynamic range than in the observations shown on Fig. 3 are used here for the color scaling to emphasize the large angular imprint on the very local galaxy clusters. The full simulation volume out to a distance of 350 Mpc is always shown. The insets show zoomed-in images of the Perseus and Hercules regions. Here a much narrower range around Perseus and A2147 is used (respectively 10 and 40 Mpc thick) to emphasize the local structures. The labels in the insets give the virial mass (in M_⊙) of the halos, together with radial velocity (in km s⁻¹) as redshift distance indicator.
