We present here a quantitative 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 (R${}_0$, V${}_0$) – 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 literature, the uncertainties on the dark matter distribution and their impact on searches of physics beyond the standard model stays sizable.

我们在此给出天体物理性质不确定性对确定银河系中暗物质分布的影响的定量估计。根据先前分析的更新，这项工作是受最近对天体相关量的新确定（例如银河参数（R${}_0$，V${}_0$）–分别来自GRAVITY合作和GAIA卫星。我们发现，即使采用这些最新的测定方法，并且与以前的文献相比，统计和系统上的不确定性范围也大大缩小，暗物质分布的不确定性及其对超出标准的物理搜索的影响模型保持可观的大小。
