    Dynamics and evolution of thick disk Globular Clusters

    The Galactic globular cluster system went and is still going through dynamical processes that require to be explored in detail. Here we illustrate how primordial massive globular clusters born in the Milky Way's disc evolved by stripping material from each other or even merging very early during their lives. These processes, previously overlooked in our Galaxy, might explain the puzzling presence of star-by-star spreads in iron content observed in massive globular clusters and should be taken into account when studying globular cluster stellar populations.
