Density profiles around filaments at z = 2, in analogy to what is shown in Fig. 9 for z = 0. Galaxy, DM, and gas profiles are shown in blue, orange, and purple, each normalised to their respective cosmic mean (grey dash-dotted line). The grey shaded area marks overdensities ≳10 that are dominated by galaxies within the filaments. Different colour shades represent different quartiles in filament width. The profiles are qualitatively similar to those at z = 0, with some minor quantitative differences.
