Phase diagrams for the cluster IT90_2 at z = 0.1. (a): all gas present in the simulated box enclosing IT90_2; (b): filaments selected by the proxy; (c): clumps identified as described in Sect. 2.2; (d): Diffuse gas located on radii over R_500, c and not organized into clumps or filaments. The color-coding identifies the mass enclosed in each single bin, normalized by the central cluster’s gas mass.
