Fast Radio Bursts are a recently discovered inexplicable astronomical phenomenon whose millisecond-timescale emission is generated by regions less than 300 kilometres across yet so luminous it is visible at cosmological distances. Using the Australian Square Kilometre Array Pathfinder we have already localised these bursts, which made the front cover of Science, and recently used them to find the missing baryonic matter in the Universe. Next, we will scrutinise these bursts at three nanosecond time resolution, reaching the timescale necessary to probe the mechanism by which their ultra-luminous radiation is generated. This project will reveal previously inaccessible properties of the radiation to unlock the secrets of how they are produced.

快速射电爆发是最近发现的一种无法解释的天文现象，其毫秒时间尺度的发射是由不到300公里的区域产生的，但如此明亮，以至于在宇宙学距离上可见。使用澳大利亚平方公里阵列探路者，我们已经定位了这些爆发，这使得科学的封面，最近用它们来寻找宇宙中丢失的重子物质。接下来，我们将以3纳秒的时间分辨率仔细检查这些爆发，达到探测其超发光辐射产生机制所需的时间尺度。该项目将揭示以前无法获得的辐射特性，以解开它们是如何产生的秘密。
