论文摘要
快速无线电爆发(FRB)是连贯的无线电发射的毫秒时刻爆发,它们的发光足以在宇宙学距离处检测到。在这篇评论中,我描述了FRB的发现,随后在我们对它们的理解方面的进步以及未来的前景。每天有成千上万的可能可观察到的FRB到达地球。它们可能起源于遥远宇宙中的高度磁性和/或快速旋转的中子星。一些FRB重复,该子类通常发生在高度磁性的环境中。两个中继器展示了循环活动窗口,与轨道时期一致。在X射线爆发期间,附近的一个FRB来自银河磁铁。某些FRB的主机星系已找到,提供了有关主机环境和宇宙的总男性含量的信息。
Fast radio bursts (FRBs) are millisecond-timescale bursts of coherent radio emission that are luminous enough to be detectable at cosmological distances. In this review I describe the discovery of FRBs, subsequent advances in our understanding of them, and future prospects. Thousands of potentially observable FRBs reach Earth every day; they probably originate from highly magnetic and/or rapidly rotating neutron stars in the distant Universe. Some FRBs repeat, with this sub-class often occurring in highly magnetic environments. Two repeaters exhibit cyclic activity windows, consistent with an orbital period. One nearby FRB was from a Galactic magnetar during an X-ray outburst. The host galaxies of some FRBs have been located, providing information about the host environments and the total baryonic content of the Universe.
