Launching the LADUMA deep HI survey
Abstract
Understanding the detailed properties of galaxies' neutral atomic gas reservoirs is a key requirement for understanding galaxies' overall cosmic evolution. Thanks to the approved 3424-hour Looking At the Distant Universe with the MeerKAT Array (LADUMA) survey, which is on the verge of taking its first data, we are now poised to extend the study of HI emission in galaxies to an unprecedented z = 1.4, when the universe was only a third of its present age. This talk will present an update on LADUMA's scientific objectives and technical challenges, with a focus on the L-band observations (probing the z < 0.58 universe) that represent the survey's first tier, as well as the multiwavelength observations of its target field that will support spectral line stacking and identification of OH megamaser interlopers. This work has been supported by the National Science Foundation through grant AST-1814421.
