Spectral maps of the ICM in ZwCl 235 (see Sect. 4.2 for details). Upper panels: the temperature (keV), pseudo-pressure (arbitrary units) and pseudo-entropy (arbitrary units) maps are shown. Relative errors are on the order of ∼20%. The overlaid white arrows mark the positions of the surface brightness edges discussed in Sect. 4.3. Lower panels: the zoomed temperature map (keV) and the pseudo-cooling time map (arbitrary units) show the distribution of the cold gas in the inner ∼50 kpc. In all panels, the white-filled, green circle marks the extent of the central X-ray source (see Sect. 4.6).
