通过球状星团合并形成星系核团簇形成

Galactic Nuclear Cluster Formation Via Globular Cluster Mergers

Roberto Capuzzo-Dolcetta

摘要:

我们应用的想法,在星系的中心区域的致密恒星系统形成通过球状星团合并的银河系的核星团的形成,那里是一个巨大的黑洞。我们的高精度N体模拟结果与银河系核团的观测特征吻合得很好,进一步证实了所谓的内星系致密系统形成的迁移模型关键词星系:核-星系:黑洞-星系:球状星团-星系:银河系-N体:模拟

英文摘要:

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
