Formation of stellar inner disks and rings in spiral galaxies through minor mergers
Recent observations show that inner disks and rings (IDs and IRs) are not preferentially found in barred galaxies, pointing to the relevance of formation...
Formation, Evolution and Disruption of Giant HII regions.
The distribution of velocity dispersion versus intensity, corresponding to the emission of the ionized gas over a giant HII region is explained within the...
We present observations and analysis of three barred S0 galaxies which contain smooth, luminous, stellar nuclear rings within their bars. These rings, which...
