This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the intergalactic medium. They could also be used as cosmic rulers to measure the expansion history of the Universe. To date, no burst has been associated with a host galaxy at a known distance, and some researchers maintain that fast radio bursts originate from more nearby sources, potentially even within our own Galaxy. The project plans to explore this hypothesis.

该项目提议首次将检测到的“快速无线电爆发”样本定位到其宿主星系（或本地祖细胞）。 “快速无线电爆发”是无线电能量的冲动爆发，其特征与来自地球的数十亿光年相一致。如果可以确定爆发的来源，它们将提供独特的工具来研究渗透到播层间介质的微弱，几乎看不见的等离子体。它们也可以用作衡量宇宙扩展历史的宇宙规则。迄今为止，尚无爆发与已知距离的宿主星系有关，一些研究人员认为，快速无线电爆发源于附近更多的来源，甚至可能在我们自己的星系内。该项目计划探讨这一假设。
