We present a comprehensive study of the distribution of matter around di ff erent populations of large-scale cosmic filaments, using the IllustrisTNG simulation at z = 0. We computed the dark matter (DM), gas, and stellar radial density profiles of filaments, and we characterise the distribution of the baryon fraction in these structures. We find that baryons exactly follow the underlying DM distribution only down to r ∼ 7Mpc to the filament spines. At shorter distances ( r < 7Mpc), the baryon…
