Globular clusters (GCs) are fossil relics from which we can obtain critical insights into the merger and accretion events that underlie hierarchical galaxy assembly. In the Local Group, GCs are found in abundance in the haloes of the Milky Way and M31, as well as in smaller dwarf galaxies of all morphological types, however no examples of intergalactic GCs are known. This is in stark contrast to the situation in large galaxy clusters, where strong interactions between galaxies have populated the space between with large populations of stripped clusters. Recently, the first systematic survey for intergalactic GCs in the Local Group has been undertaken, and we propose to determine the nature of the candidates identified by this search by means of GMOS imaging. Uncovering a heretofore unknown population of such objects would have important implications for our understanding of the interaction and merger history of Local Group galaxies back to early epochs.
