Galaxies with stellar masses log(M) ≥ 11 M have a systematically higher Hɪ fraction near filaments than the control sample. The greatest difference is 0.75 dex, which is 5.5θ difference at mean projected densities of 1.45 galaxies Mpc⁻². We suggest that this is evidence for massive galaxies accreting cold gas from the intrafilament medium that can replenish some Hɪ gas. This supports cold mode accretion where filament galaxies with a large gravitational potential can draw gas from the large-scale structure.]]> Wed 04 Sep 2019 09:39:57 AEST ]]> WALLABY - an SKA Pathfinder Hi survey https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42725 Thu 01 Sep 2022 13:18:22 AEST ]]>
