Dwarf ellipticals (dEs) are the most numerous galaxy population in nearby dense environments. These low mass systems are very sensitive to both internal and external processes and are therefore ideal to test theories of galaxy formation and evolution. However, their low surface brightness makes detailed observations challenging. Here we present the first results based on FORS/VLT optical spectroscopy of fifteen dEs. We compare age and metallicity estimates from full spectrum fitting with those… CONTINUE READING
