Abstract

It has been 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 still surrounded by a distinct and detectable stellar population similar to that of their progenitor galaxies. We have designed a systematic photometric survey of Galactic globular clusters to unveil the possible remnants of the systems where they were formed and estimate their contribution to the Galatic halo.
