Observations in different wavebands. From top to bottom: distribution of galaxies in the 2MRS catalog, X-ray surface brightness in the ROSAT 1.5 keV band (R6 + R7 = 0.76 − 2.04 keV), and Compton-Y map based on Planck data (produced with the MILCA algorithm Planck Collaboration XXII 2016) with the CO mask by Khatri (2016). The insets show zoomed-in images of the Perseus and Hercules regions. The labels in the insets give the Name together with radial velocity (in km s⁻¹) as redshift distance indicator. The yellow labels indicate clusters that are outside the slice used in the simulations shown in Fig. 4.
