Accreted versus In Situ Milky Way Globular Clusters [PDF]

, 2010
Here we examine the Milky Way's GC system to estimate the fraction of accreted versus in situ formed GCs. We first assemble a high quality database of ages and metallicities for 93 Milky Way GCs from literature deep colour-magnitude data.
