TSI Seminar

The atomic gas (HI) content of nearby galaxies provides important insight into how they form and evolve within the standard cosmology. In this talk, I will highlight some of my group's recent progress towards leveraging new facilities and surveys into statistical samples of gas-rich galaxy detections. I will first focus on searches for the low-mass end of the star forming galaxy population with targetted and widefield surveys, as well as prospects for dim and dark galaxy population studies with the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD). I will then describe some of the first spatially resolved population studies of Milky Way-like HI disks using the widefield WALLABY survey that is now underway on the Australian SKA Pathfinder (ASKAP). This work paves the way for mapping HI disks across cosmic time with SKA-Mid when it comes online early in the next decade.
