Upper panels: Mean distance to the cosmic web filaments, measured in projection (2D), for starburst galaxies (purple), MS galaxies mass-matched to starbursts (blue), and quenched galaxies mass-matched to the complete MS sample (red) as a function of redshift for four different selection criteria in SIMBA, with our reference case on the left. The dotted lines show the same quantities without mass-matching. The upper left boxes show the same trends for the median values. Lower panels: Fraction of starburst galaxies with respect to MS galaxies as a function of redshift. Starbursts are, on average, closer to filaments than MS galaxies at high redshift but exceed the MS distance at z ≃ 1. The fraction of SFGs rises with redshift and stabilises around z ≃ 1.5, while the starburst fraction remains roughly constant at ∼10%, with a modest enhancement for galaxies near filaments at z > 1.
