Abstract:

UNC researchers Mark Norris and Sheila Kannappan are analyzing the Hubble Space Telescope archives to compare the ages of dwarfs and their host galaxies. If they are both of the same age, then the dwarfs are probably giant globular clusters; if they are of different ages, then the dwarf was probably born as a galaxy and later pulled into another orbit.
