Abstract:

It is commonly assumed that low surface brightness (LSB) galaxies are dormant and quiescent systems. These conclusions are however based on observations of a large number of distant LSB galaxies. Here we show some first results of a study of very nearby galaxies, which suggest that the featureless systems observed at large distances resolve into complex and chaotic systems. We also present new data on NGC 6822, a dwarf galaxy in our Local Group, and argue that this object would be classified as a LSB galaxy if it were at a larger distance. It thus puts us in the unique position of being able to study a LSB galaxy at very high resolution, enabling us to get a better picture of the interaction between ISM, stars and dark matter in low density galaxies.
