摘要:

我们总结了最近的核星团的调查结果。该调查的目的是了解核恒星团簇形成机制和限制黑洞的存在,使用自适应光学辅助积分场光谱学,光学光谱学和HST成像在13个星系在5百万秒差距。我们讨论的形成历史的核星团和可能检测到一个中等质量的BH在NGC 404,最近的S0星系。

英文摘要:

We summarize the recent results of our survey of the nearest nuclear star clusters. The purpose of the survey is to understand nuclear star cluster formation mechanisms and constrain the presence of black holes using adaptive optics assisted integral field spectroscopy, optical spectroscopy, and HST imaging in 13 galaxies within 5 Mpc. We discuss the formation history of the nuclear star cluster and possible detection of an intermediate mass BH in NGC 404, the nearest S0 galaxy.
