在直接暗物质（DM）探测实验中预测信号需要了解当地晕的天体物理结构。这种理解中的任何不确定性都会直接影响到所有的实验结果。然而，我们的地面实验能够研究这种相同的天体物理依赖性，事实上，这是我们在亚毫秒差距尺度上对局部晕的唯一探测。如果方向敏感实验是可行的，这在WIMP暗物质的情况下是最好的，但需要新的速度分布参数化模型的独立要求。对于轴子来说，前景要大得多，与天体测量探测器相比，占星仪将能够更好地测量局部DM分布。
Predicting signals in direct dark matter (DM) detection experiments requires an understanding of the astrophysical structure of the local halo. Any uncertainty in this understanding will feed directly into all experimental results. However our terrestrial experiments are in a position to study this same astrophysical dependence, and in fact represent our only probe of the local halo on sub-milliparsec scales. This is best achieved in the case of WIMP dark matter if directionally sensitive experiments are feasible, but requires novel parameterizations of the velocity distribution to make model independent claims. For axions the prospects are much greater, haloscopes would be able to make better measurements of the local DM distribution than astrometric probes.
