Dependences of various physical quantities on distance from the cluster center. Top left panel: Median overdensity of the gas outside the virial boundary of the cluster inside (red symbols) and outside (green symbols) the filaments. The dashed blue (orange) line shows ρ ∝ r^−1.6 (ρ ∝ r⁻⁴) approximation for the density profile inside (outside) filaments. The horizontal dash-dotted line shows the median overdensity within the filaments at radii 4r₂₀₀ <  r <  7r₂₀₀. The mean cosmic density is denoted with a horizontal dotted line. The approximate radial range of the elongated virial boundary is indicated with the vertical dashed lines. Top right panel: Same as left panel, but for the median temperature. The dashed lines indicate the piece-wise power-law approximation to the temperature profile in different zones (IF1-3 and OF1-2, see Sect. 4.2). Bottom left panel: Same as top panels, but for the median radial velocity towards the cluster. The blue curve indicates the free-fall velocity given by the mass of the cluster. Bottom right panel: Median gas and ram pressure outside the virial region of the cluster as a function of the distance from the cluster centre for the gas within (square symbols) and outside (diamond symbols) filaments.
