中文摘要
快速射电暴是最近发现的一种难以解释的天文现象,其毫秒时间尺度的发射是由直径不到300公里的区域产生的,但在宇宙距离上却如此明亮。利用澳大利亚平方公里阵列探路者,我们已经确定了这些爆发的位置,这些爆发上了《科学》杂志的封面,最近还利用它们找到了宇宙中失踪的重子物质。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必需的时间尺度。这个项目将揭示以前无法接近的辐射特性,以解开它们是如何产生的秘密。
英文摘要
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.
