Neutral Hydrogen in Nearby Dwarf Galaxies
  Here I briefly highlight our studies of the gas content, kinematics and star
formation in nearby dwarf galaxies (D < 10 Mpc) based on the `Local Volume HI
Survey' (LVHIS, Koribalski et al. 2018), which was conducted with the Australia
Telescope Compact Array (ATCA). The LVHIS sample consists of nearly 100
galaxies, including new discoveries, spanning a large diversity in size, shape,
mass and degree of peculiarity. The hydrogen properties of dwarf galaxies in
two nearby groups, Sculptor and CenA / M83, are analysed and compared with many
rather isolated dwarf galaxies. Around 10% of LVHIS galaxies are transitional
or mixed-type dwarf galaxies (dIrr/dSph), the formation of which is explored. -
I also provide a brief update on WALLABY Early Science, where we focus on
studying the HI properties of galaxies as a function of environment. WALLABY
(Dec < +30 degr, z < 0.26) is conducted with the Australian SKA Pathfinder
(ASKAP), a 6-km diameter array of 36 x 12-m dishes, each equipped with
wide-field (30 sq degr) Chequerboard Phased Array Feeds.
