Upper limits on the dark matter content in globular clusters

Understand

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.
