Title: Redshifts in the LADUMA Field to z ~ 0.6

Abstract: Understanding the history of galaxy evolution requires understanding galaxies' neutral atomic gas. As an approved, high-priority project using MeerKAT, the South African precursor to the Square Kilometre Array (SKA), the LADUMA (Looking at the Distant Universe with the MeerKAT Array) survey will probe the H, line, initially to $z sim 0.6$ and eventually to $z sim 1.4$, both in individually detected galaxies and in stacks at the precise positions and redshifts of optically selected samples. Here we propose to extend our AAOmega redshift survey in the LADUMA field to fainter sources in the range .4 leq z leq 0.6$. By facilitating stacking, these data will help address how galaxies' evolving H, content relates to their halo and stellar masses, and to the gas mass in absorption-line systems. They will also underpin deeper redshift surveys (probing to $z sim 1.4$), as well as an ALMA CO snapshot survey that will enable studies of the baryonic Tully-Fisher and fundamental metallicity relations. We request no proprietary period and commit to making all redshift measurements public.
