The puzzling assembly of the Milky Way halo – contributions from dwarf Spheroidals and globular clusters
... Abstract. While recent sky surveys have uncovered large numbers of ever fainter Milky Way satellites, their classification as star clusters, low-luminosity galaxies, or tidal overdensities remains often unclear. ...
