Recent studies show that most dwarf elliptical galaxies (dE) in nearby clusters possess nuclear star clusters. Earlier studies used photographic plates and frequently missed the faint nuclei in dEs.
For the first time, we are able to identify nuclei in a large number of dE galaxies in the Coma cluster with ACS/HST Coma Cluster Treasury Survey images. This data allows us to compare the properties of nuclei to their underlying galaxies, to study the properties of galaxies with and without the nuclei, and to compare dE and dE,N galaxies to those studied in the Fornax and the Virgo cluster. In order to shed some light on the formation mechanism of nuclei in dE galaxies we first identify nuclei in dE galaxies using aperture photometry and 2D Sersic profile fitting. We then, investigate relations between the nuclei and the underlying galaxy properties and compare them to previous studies done in Fornax and Virgo. We show relations between the nuclei color and the underlying galaxy light, difference in color between non-nucleated and nucleated dE's, and we investigate whether nucleated dE's are more strongly concentrated toward the cluster center as found in earlier studies.
