Abstract:
In this talk, I will first summarise my PhD thesis work
focusing on two HI absorption surveys. One was undertaken with the
ATCA, targetting nearby (z < 0.1) compact radio galaxies, thought to
represent young or retriggered radio AGN. The second was during early
science commissioning with the ASKAP-BETA prototype array towards
dust-obscured quasars, which represent a transitional stage in galaxy
evolution. In the second half of my talk I will introduce LADUMA, the
Looking At the Distant Universe with the MeerKAT Array HI emission
survey. To assist the analysis of this survey I present early results
of working with the cosmological hydrodynamic MUFASA and SIMBA
simulations. This includes the development of a new tool, pyloser, to
compute galaxy photometry and spectra from simulations for individual
galaxies, and an investigation of the Baryonic Tully Fisher
relationship. This work will assist not only with the interpretation
and analysis of the LADUMA survey results, but additionally test
galaxy formation and evolution models, and benefit other SKA precursor
science surveys.
