I present a kinematic analysis of the globular cluster (GC) system in the giant elliptical galaxy (gE) M60 in the Virgo cluster.<br />
Using the photometric and spectroscopic database of M60 GCs, we have investigated the kinematics of the GC system: the rotation, the velocity dispersion, and the velocity anisotropy. Similar analysis is carried out for other gEs (M49, M87, NGC 1399, NGC 5128, and NGC 4636) using the data in the literature. We compare the kinematic properties of these GC systems and discuss the implication of these results for the formation models of the GC system in gEs.<br />
