Abstract:
We present a systematic analysis on the possible presence of dark mass
components inside globular clusters (GCs). A spherical Jeans analysis is
applied to the stellar kinematics of 9 nearby GCs. On top of the mass
distribution provided by the luminous stellar component, we add either dark
matter (DM), described by an NFW mass profile, or an intermediate mass
black-hole (IMBH), described by a point-like mass. Their existence would have
important implications in the context of indirect DM searches. After profiling
over the stellar parameters, we find no evidence neither for DM nor for IMBH.
Upper limits on the two components are reported.
