Off-center Nuclei in Dwarf Elliptical Galaxies
We have searched for off-center nuclei in 78 "nucleated" dwarf elliptical (dE,N) galaxies, drawing on digitized photographic images from a previous study of Virgo cluster dwarfs. The search is based on a simple algorithm which compares the center coordinates of a series of outer elliptical isophotes with the position of the galaxy's nucleus. Monte Carlo simulations of the measuring procedure are used to assess random and systematic errors. Roughly 20% of all dwarf nuclei in the sample...[Show more]
