Mean-averaged density profiles of galaxies, dark matter, and gas around filaments in EAGLE at z = 0. Different shades represent different filament width quartiles as indicated. All profiles are mean-averaged across the relevant filament segments and normalised to their respective cosmic mean (grey dash-dotted line). The different profiles agree broadly with each other, with the galaxies most concentrated near the filament spine while the gas is most extended. Even in the thickest quartile, the average profiles reach the cosmic mean at < 3 Mpc from the spine.
