Weaver arXiv:2605.02999v1 Announce Type: new Abstract: Direct observational constraints on how galaxies acquire their gas remain remarkably limited, hindering our understanding of the baryon cycle. We present a search for down-the-barrel ion{Na}{i} D absorption towards 15.6 million galaxies at $z 50$ km/s. We find strong evidence for a large population of low-velocity, infalling absorbers with velocities $sim$20 km/s in edge-on galaxies, consistent with radial inflows predicted in simulations. The stronger correlation in early-type galaxies between inflow velocity and stellar velocity dispersion, compared to that with stellar mass, suggests that a portion of these inflows may be associated with accreting satellites. These results reveal the multiple pathways in which galaxies accrete gas at redshift $z arXiv:2605.02999v1 Announce Type: new Abstract: Direct observational constraints on how galaxies acquire their gas remain remarkably limited, hindering our understanding of the baryon cycle.
