KECK SPECTROSCOPY OF DWARF ELLIPTICAL GALAXIES IN THE VIRGO CLUSTER

Marla Geha, Puragra Guhathakurta, Roeland P. van der Marel

Abstract

Keck spectroscopy is presented for four dwarf elliptical galaxies in the Virgo Cluster. At this distance, the mean velocity and velocity dispersion are well resolved as a function of radius between 100 to 1000 pc, allowing a clear separation between nuclear and surrounding galaxy light. We find a variety of dispersion profiles for the inner regions of these objects, and show that none of these galaxies is rotationally flattened. 1
