TL;DR
This paper investigates the formation of the Milky Way's Nuclear Star Cluster through N-body simulations, supporting the hypothesis that it formed via the merging of globular clusters in the galaxy's core.
Contribution
It provides simulation-based evidence for the globular cluster merging hypothesis as the origin of the Milky Way's Nuclear Star Cluster.
Findings
N-body simulations support the merging hypothesis.
Globular cluster mergers can form nuclear star clusters.
The Milky Way's nuclear cluster likely formed through this process.
Abstract
In the center of the Milky Way, as well as in many other galaxies, a compact star cluster around a very massive black hole is observed. One of the possible explanations for the formation of such Nuclear Star Clusters is based on the 'merging' of globular clusters in the inner galactic potential well. By mean of sophisticated N-body simulations, we checked the validity of this hypothesis and found that it may actually has been the one leading to the formation of the Milky Way Nuclear Star Cluster.
