Descripción
The picture of building the Milky Way halo from merging protogalactic
fragments is considered the local manifestation of the hierarchical
galaxy formation process. In this scenario, some observational evidences
have suggested that the outer young Galactic halo globular cluster
population might be associated (or even the nuclei) to tidal disrupted
dwarf spheroidals, now extinct galaxies. If this hypothesis is true,
these systems might be surrounded by a distinct and still detectable
stellar population. We have carried out a systematic observation of
Galactic globulars covering the galactocentric distance range 10 <
RGC< 40 kpc in both hemispheres. We have used wide field
instruments both in La Palma and in La Silla observatories to obtain
deep photometry of wide areas around these globulars to unveil the
possible remnants of their progenitor dwarf galaxies.
