| Description: | Understanding how galaxies form and evolve requires knowledge of their cold gas component, and how this depends on their structural and star formation properties, as well as the large-scale environment. Significant effort has gone into systematic surveys of cold gas in the local Universe, resulting in a network of scaling relations that connect atomic and molecular gas content of galaxies to their global properties and environments.
In today's colloquium, I will present some of these scaling relations and discuss their implications for galaxy evolution studies. I will also show preliminary results from the ongoing WALLABY survey on the Australian SKA Pathfinder, and conclude with some future outlooks. |
