论文摘要
银河系是否包含微型FRB的来源，类似于已知FRB的较低能量事件，但仅在银河系距离下可检测到？这个问题的答案对于确定FRB来源的性质至关重要。在典型的（$ 10 $ kpc）的银河系距离上，爆发比在“宇宙学”（$ z = 1 $）距离处更明亮。如果存在，则可以在月球反射后检测到银河系微杆的辐射，或者在其速率集上的上限，凝视着月球的射电望远镜的速度（20 m时为20 m）。它将具有全天的灵敏度。直接检测（通过焦距或偶极子）和月球散射辐射之间的延迟将限制爆发的位置到狭窄的弧线。
Does the Galaxy contain sources of micro-FRB, lower energy events resembling the known FRB but detectable only at Galactic distances? The answer to this question is essential to determining the nature of FRB sources. At typical ($10$ kpc) Galactic distances a burst would be about 117 dB brighter than at a "cosmological" ($z = 1$) distance. The radiation of Galactic micro-FRB, if they exist, could be detected after Lunar reflection, or an upper bound on their rate set, by a modest (20 m at 1.4 GHz) radio telescope staring at the Moon. It would have all-sky sensitivity. The delay between detection of direct (by STARE2 or dipoles) and Lunar-scattered radiation would restrict a burst's position to a narrow arc.
