Title: Tidal disruption of Globular Clusters in dwarf galaxies Abstract: A large fraction of Globular Clusters (GCs) in the external galactic regions is thought to have been formed in satellite galaxies that were accreted onto the hosts at early epochs. However, not much is known about the formation and evolution of those GCs prior to their accretion. Here I explore the tidal evolution of GCs in the dark matter haloes of satellite galaxies within the CDM framework. The goal is twofold: on the one hand, we examine what GCs are expected to survive in the tidal field of satellite galaxies, as those represent the population that linger today in the stellar halo of the Milky Way. On the other hand, for those clusters that are tidally disrupted we study the spatial and kinematical distribution of their debris in the host dwarf galaxy. We show that cluster debris may provide strong probes of the shape of the dark matter halo potential wherein dwarf galaxies are thought to be embedded, as well as explain the presence of cold substructures and stellar over-densities detected in several dwarf spheroidal galaxies of the Milky Way.
