Tracing the outer edges of galaxy disks
Baerbel Koribalski (ATNF)
What determines the size and shape of galaxy disks ? I will present a detailed look at the gas distribution and kinematics of individual nearby galaxies in a range of environments. The outskirts of galaxy disks are best traced in the HI 21-cm line and display the impact of physical processes such as accretion and ram pressure stripping. Dwarf galaxies are particularly susceptible to their environment and are often seen in the act of transformation.
