论文摘要
快速无线电爆发（FRB）代表了最近过去最令人兴奋的天体物理发现之一。对他们的低频排放的研究，仅在发现后大约十年后才有效地拾取，这有助于塑造了该领域，这要归功于迄今为止的一些最重要的检测。特别是由钟声/FRB望远镜进行的400至800 MHz的观察结果，导致在1年以上发现了〜500 FRB，其中约有20个重复来源。低频的检测发现了附近的人群，我们可以通过连续监测和有针对性的运动进行详细研究。最新，最重要的发现包括：周期性，无论是在中继器的日期和明显不重复的来源的毫秒级别；从银河磁场检测到类似FRB的爆发；以及FRB在附近星系中的球状簇中的定位。低频对人口的系统研究对于围绕FRB的环境的表征以及在全球范围内了解当地宇宙的环境至关重要。这篇综述旨在概述导致当前各种低频研究种类繁多的努力，并将其纳入共同环境，以追踪可能在该领域未来进步的可能路线图。
Fast radio bursts (FRBs) represent one of the most exciting astrophysical discoveries of the recent past. The study of their low-frequency emission, which was only effectively picked up about ten years after their discovery, has helped shape the field thanks to some of the most important detections to date. Observations between 400 and 800 MHz, carried out by the CHIME/FRB telescope, in particular, have led to the detection of ~500 FRBs in little more than 1 year and, among them, ~20 repeating sources. Detections at low frequencies have uncovered a nearby population that we can study in detail via continuous monitoring and targeted campaigns. The latest, most important discoveries include: periodicity, both at the days level in repeaters and at the millisecond level in apparently non-repeating sources; the detection of an FRB-like burst from a galactic magnetar; and the localisation of an FRB inside a globular cluster in a nearby galaxy. The systematic study of the population at low frequencies is important for the characterisation of the environment surrounding the FRBs and, at a global level, to understand the environment of the local universe. This review is intended to give an overview of the efforts leading to the current rich variety of low-frequency studies and to put into a common context the results achieved in order to trace a possible roadmap for future progress in the field.
