Abstract:
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 the 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.
