论文摘要
我们使用自己的银河系（银河系）作为测试台测试了Yukawa的校正，利用自己的银河系（The Mirky Way）。我们将Yukawa强度和范围和暗物质剖面参数作为自由参数，并比较了凸起，气体和磁盘组件的几种形态，也使用贝叶斯模型选择标准。我们对银河系的可见（重型）组件以及重力电位的示踪剂（旋转曲线）采用了最新数据集。 We find that the data are consistent with the Newtonian potential, and constrain the Yukawa coupling $β$ to be negative and $λ$ to range along the curve $λ= a|β|^{c}$ with $a = (0.77 \pm 0.06)$ kpc and $c = -0.503\substack{+0.016 \\ -0.019}$.
We test a Yukawa correction to the Newtonian potential, making use of our own Galaxy - the Milky Way - as a testbed. We include as free parameter the Yukawa strength and range and the dark matter profile parameters, and compare several morphologies for the bulge, gas, and disk components, also using Bayesian model selection criteria. We employ up-to-date datasets for both the visible (baryonic) component of the Milky Way, and for the tracers of the gravitational potential (the Rotation Curve). We find that the data are consistent with the Newtonian potential, and constrain the Yukawa coupling $β$ to be negative and $λ$ to range along the curve $λ= a|β|^{c}$ with $a = (0.77 \pm 0.06)$ kpc and $c = -0.503\substack{+0.016 \\ -0.019}$.
