Dwarf galaxies in nearby Southern groups

Côté, Stéphanie

Description

This thesis describes a successful survey to find dwarf irregular galaxies in the two most nearby southern groups of galaxies, the Sculptor group at 2.5 Mpc and the Centaurus A group at 3.5 Mpc. Candidates were selected from a visual search on ESO SRC J films, then observed in neutral hydrogen (HI) at Parkes, as well as in Ha. In the Sculptor group 12 dwarfs are detected, and in Centaurus A 20 (from which 21 were already known members), yielding a dwarf-to-giant ratio of roughly 3. Some...[Show more]
