TL;DR
This paper uses high-precision N-body simulations to support the migratory model, suggesting that the Milky Way's nuclear star cluster formed through globular cluster mergers in the presence of a central black hole.
Contribution
It provides detailed simulation evidence for the formation of the Milky Way's nuclear star cluster via globular cluster mergers, including the influence of a central black hole.
Findings
Simulation results match observed properties of the Milky Way's nuclear cluster.
Supports the migratory model for nuclear star cluster formation.
Highlights the role of globular clusters in galaxy nucleus evolution.
Abstract
We apply the idea that dense stellar systems in the central region of galaxies are formed via globular cluster mergers to the formation of the nuclear star cluster of the Milky Way, where a massive black hole is present. Our high precision N-body simulations show a good fit to the observational characteristics of the Milky Way nuclear cluster, giving further reliability to the so called migratory model for the formation of compact systems in the inner galaxy regions keywords galaxies: nuclei - galaxies: black holes - galaxies: globular clusters - galaxies: Milky Way - N-body: simulations
