论文摘要
我们在这里介绍了天体物理性质不确定性对我们银河系中暗物质分布的确定的定量,准确的估计。基于对先前分析的更新,这项工作是通过重力协作和Gaia卫星的最新确定的天体物理量(例如银河参数(R0,V0))的新确定。我们发现,即使有了这些最先进的决心和一系列不确定性(无论是统计还是系统的),在先前的工作中,对暗物质分布的不确定性以及它们对标准模型以外的物理学搜索的影响都保持较大。
We present here a quantitative, accurate estimate of the impact of uncertainties of astrophysical nature on the determination of the dark matter distribution within our Galaxy, the Milky Way. Based on an update of a previous analysis, this work is motivated by recent new determinations of astrophysical quantities of relevance -- such as the Galactic parameters (R0,V0) -- from the GRAVITY collaboration and the GAIA satellite, respectively. We find that even with these state-of-the-art determination and a range of uncertainties -- both statistical and systematic -- much narrowed with respect to previous work, the uncertainties on the dark matter distribution and their impact on searches of physics beyond the standard model stays sizable.
