The Ages and Metallicities of Globular Clusters and Nuclei in dE Galaxies
Bryan Miller (Gemini Obs.)

We present results of a Gemini/GMOS program to measure spectroscopic metallicities and ages of globular clusters and nuclei in dwarf elliptical galaxies in the Virgo and Fornax Clusters. Preliminary results indicate that the globular clusters are old and metal-poor, very similar to the globular clusters in the Milky Way halo. The nuclei tend to be more metal-rich than the globular clusters but less metal rich and older, on average, than the stars in the bodies of the galaxies. The [alpha/Fe] ratio appears to be solar for the globulars, nuclei, and dEs, but the uncertainties do not exclude some globular clusters from being enhanced in alpha elements.
