Abstract
We present preliminary results of an extensive study of the fundamental properties of dwarf elliptical galaxies (dEs) in the Coma cluster. Our study will combine HST surface photometry with ground-based UBRIJK photometry and optical spectroscopy. The combined data set will be used to investigate the intrinsic correlations among global parameters in cluster dEs, including the Fundamental Plane, color-magnitude, Faber-Jackson's, Kormendy's, and velocity dispersion vs line strength indices. These empirical correlations have provided important constraints to theoretical models of galaxy formation and evolution for "normal" ellipticals. Although dEs are the most abundant galaxy population in clusters their properties remain, however, largely unknown. Our study aims to provide an essential reference for testing current theories on the formation and evolution of dEs in clusters, and understanding their relation to more massive ellipticals.
Description
Conference on Star Formation through Time (2002. Granada, Spain). R.G. would like to thank the organizing committee for such an excellent meeting to honor our friend Roberto, both from the point of view of the outstanding scientific results presented at the meeting and the superb atmosphere of camaraderie. As Roberto likes to say: “there is nothing like doing good science among friends”.
