Density profiles of galaxies (blue), dark matter (DM; orange), and gas (purple) around filaments reconstructed from the galaxy distribution (solid lines) of EAGLE at z = 0. Equivalent profiles around a matched sample of DM-based filaments are shown as dashed lines for comparison. For all three components, the profiles around galaxy-based filaments agree quite well with their DM counterparts in the central ≈0.5 Mpc but are significantly more extended at larger radii.
