Mass distribution of large-scale structures. Following Artale et al. (2022), the mass distribution within LSS substructures in the z = 0 snapshot of TNG100-3 when binned according to our metric. Yellow, cyan, and purple portions of the curve indicate mass within halos, filaments, and voids, respectively, according to our boundaries (dashed and dot-dashed lines). ρ_c is the cold dark matter density, and ρ_cr is the present-day critical density of the Universe.
