Bi-Qing Colloquium: ASKAP WALLABY - dwarf galaxies in the local Universe

The Australia Telescope National Facility Colloquium
15:00-16:00 Wed 19 Oct 2022



Low-mass, or dwarf, galaxies are the primary source of ionising photons during the epoch of reionisation and they are the building blocks of galaxies in early Universe. Thus, they play an important role as the strongest test for the standard Cold Dark Matter model on the smallest scale.
In this talk, I will present the results and goals of two ongoing dwarf galaxies related projects that utilise ASKAP WALLABY data in conjunction with other legacy multiwavelength data. The two main studies are (1) probing role of galaxy
interactions in quenching at low-mass end and (2) probing the formation mechanisms
of low-surface brightness 'dwarf' galaxies (ultra diffuse galaxies) from the HI perspective.
