Looking At the Distant Universe with MeerKAT and SALT
S.-L. Blyth · 2016
With the upcoming LADUMA (Looking At the Distant Universe with MeerKAT Array) survey we are aiming to probe the neutral atomic hydrogen (HI) content of galaxies over two-thirds of the age of the universe with the aim to investigate the role of cold gas in the evolution of galaxies over cosmic time.We will use the MeerKAT radio telescope to make these observations which will be the deepest measurements of HI in emission in galaxies prior to the SKA coming online.Here we present an overview of the scientific motivation for the survey and some of the science questions we hope to address.With many of our investigations relying on a combination of the radio observations with other multi-wavelength data, we envision that SALT, due to its location and suite of capabilities, will be instrumental in helping us to achieve our goals.
