Description
The SKA is now under construction, and its two main mid-frequency precursor instruments, the Australian SKA Pathfinder and MeerKAT radio telescopes, are in full swing. In particular, ASKAP is conducting all-sky surveys of the neutral hydrogen (HI) content in emission and absorption (WALLABY and FLASH surveys respectively), while MeerKAT probes select fields or targets to far deeper levels thanks to its superior sensitivity (LADUMA, MIGHTEE-HI, and MALS). As these numerous surveys progress, we can employ hydrodynamical simulations to make predictions and compare to preliminary results, and in turn inform galaxy evolution models employed in simulations. I present ongoing efforts to produce Simba/Simba-C-based mock samples of HI datacubes from SKA precursor surveys, and present comparisons between those with observational studies of HI asymmetry through work by the ASymba collaboration, as well as scaling relations such as the baryonic Tully-Fisher relation. These methodologies developed now for the SKA precursor surveys will be applicable to the SKA era.
