Near IR imaging of Centaurus group dwarf elliptical galaxies
Detailed studies of dwarf galaxies in the Local Group have revealed an amazing diversity in their star formation histories. Young and intermediate-age stellar populations are observed in some gas-poor dwarf ellipticals, like Fornax and Carina, where naively one would have expected to find preferentially old stellar populations. There are evidences that the environment might drive the evolution of these galaxies. In order to explore stellar populations in dwarf galaxies in an environment denser...[Show more]
