Left column: subhalos (black dots) and DisPerSE skeletons (red lines) with several significance levels (from top to bottom: σ_p = 0, 2, 5). Right column: superimposition of some thresholded probability maps obtained by T-ReX and DisPerSE skeletons (red lines) with several significance levels (from top to bottom: σ_p = 0 and Γ_0.0(I), σ_p = 2 and Γ_0.1(I), σ_p = 5 and Γ_0.25(I)). Resolution of the maps provided by T-ReX is 250 Kpc h⁻¹. Shaded blue and orange areas highlight some differences between results discussed in Sect. 6.1.1.
