What Can the Radial Surface Brightness Profiles of Galaxy Discs Tell Us About Their Evolution?,ere the inner disc slope changes to a more abrupt outer slope have increased with epoch, but that at all epochs this radius has the bluest, i.e. the youngest stellar population. This can be explained via models which combine stellar migration due to non-axisymmetry with continuous star formation due

Regarding the bulge region we find that the ages and metallicities are younger and more metal rich, at a given ., than the bulges of unbarred galaxies. The bulges of the barred galaxies in our sam

The current volume affords readers a unique perspective on galaxies by probing the thoughts of some of the greatest astronomers of our age. Contributions focus on galaxies from within our Local Group to those in our high redshift Universe. Approximately 4

Masks of interstellar dust affect our measurements within galaxies, on scales ranging from individual supernovae to the galaxies themselves.
