论文摘要
在不到十年的时间里，快速无线电爆发已从单一的辩论好奇心变成了具有既定的宿主星系和能量尺度的多样化的婚外恋。尽管广泛的模型仍然可行，但FRB的中央发动机可能涉及能量的年轻磁铁，这是由于最近发现了与这些外层状爆发的银河类似物所证实的那样。在这里，我们简要介绍了快速无线电爆发，重点是观察这些神秘事件的最新进展，我们对它们的中央发动机的理解以及它们用作播种介质的探针。我们警告不要急于对所有FRB的机制和分类进行判断：在这一点上，可能存在一个主要的中央发动机，以及无线电爆发是由许多不同机制产生的一般特征的可能性。我们还强调了改进银河系和银河系光环的建模的重要性，否则它们会对每条FRB的视线造成系统错误。快速无线电爆发的科学未来似乎很明亮。
In less than a decade, fast radio bursts have gone from a single debated curiosity to a diverse extragalactic population with established host galaxies and energy scales. While a wide range of models remain viable, the central engines of FRBs are likely to involve energetic young magnetars, as confirmed by the recent discovery of a Galactic analog to these extragalactic bursts. Here we provide a brief introductory review of fast radio bursts, focusing on the rapid recent progress in observations of these enigmatic events, our understanding of their central engines, and their use as probes of the intergalactic medium. We caution against a rush to judgement on the mechanisms and classification of all FRBs: at this point, it remains plausible that there could be one dominant central engine, as well as the possibility that radio bursts are a generic feature produced by many different mechanisms. We also emphasize the importance of improved modeling of our Galaxy and Galactic halo, which otherwise impose systematic errors on every FRB line of sight. The future of science with fast radio bursts appears bright.
