标题： Search for axions in streaming dark matter

摘要： 一种新的搜索策略用于探测难以捉摸的暗物质（DM）轴子。 该想法基于流式暗物质轴子，其通量可能由于引力透镜效应而暂时极大地增强。 如果太阳或某个行星（包括月球）位于朝向地球位置传播的暗物质流方向上，就可能发生这种情况。 对轴子晕器的实验要求是宽频性能结合快速轴子静质量扫描模式，这是可行的。 一旦这两种条件在晕器中得到实现，轴子搜索可以像以前一样继续进行。 有趣的是，一些新的暗物质轴子探测器默认是宽频的。 为了避免错过潜在短时信号的实际不可预测的时间，需要一个协调的轴子天线网络，最好是全球分布的。 这里针对轴子提出的推理在一定程度上也适用于其他暗物质候选者，如WIMPs。 显示英文摘要

摘要： A new search strategy for the detection of the elusive dark matter (DM) axion is proposed. The idea is based on streaming DM axions, whose flux might get temporally enormously enhanced due to gravitational lensing. This can happen if the Sun or some planet (including the Moon) is found along the direction of a DM stream propagating towards the Earth location. The experimental requirements to the axion haloscope are a wide-band performance combined with a fast axion rest mass scanning mode, which are feasible. Once both conditions have been implemented in a haloscope, the axion search can continue parasitically almost as before. Interestingly, some new DM axion detectors are operating wide-band by default. In order not to miss the actually unpredictable timing of a potential short duration signal, a network of co-ordinated axion antennae is required, preferentially distributed world-wide. The reasoning presented here for the axions applies to some degree also to any other DM candidates like the WIMPs.
