论文摘要
我们对球状簇（GCS）内部可能存在的黑质量成分可能存在进行系统分析。球形牛仔裤分析应用于附近9个GC的恒星运动学。在发光恒星成分提供的质量分布的顶部，我们添加了由NFW质量谱描述的暗物质（DM），或者是由点样质量描述的中间质量黑洞（IMBH）。它们的存在将在间接DM搜索的背景下具有重要意义。在分析了恒星参数之后，我们没有发现DM也没有证据表明IMBH。报告了两个组件的上限。
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. After profiling over the stellar parameters, we find no evidence neither for DM nor for IMBH. Upper limits on the two components are reported.
