Fast radio bursts (FRBs) are brief, highly dispersed bursts detected in the radio band that originate from cosmological distances. The only such event detected in the Milky Way Galaxy, FRB 20200428D—which was associated with an X-ray burst emitted by a magnetar named SGR J1935+2154—revealed the first case of a multiwavelength counterpart of an FRB. Counterparts in other wavelengths accompanying or following FRBs, as well as the bright emission associated with the progenitor of the FRB engine, have been proposed in various FRB models, but no robust detection has been made so far. In general, FRBs as we know them are not favored multimessenger emitters. Nonetheless, possible neutrino and gravitational wave emission signals associated with FRBs or FRB-like events have been discussed in the literature. Here I review these suggested multiwavelength and multimessenger counterparts of FRBs or FRB-like events and the observational progress in searching for these signals. Topics include multiwavelength (X-rays, γ-rays, optical) emission and neutrino emission from FRBs within the framework of the magnetar source models and possible FRB-like events associated with gravitational waves.

快速射电暴的多波长和多信使对应物


快速射电暴 （FRB） 是在射电波段中探测到的短暂、高度分散的暴发，源自宇宙学距离。在银河系中检测到的唯一此类事件 FRB 20200428D——它与名为 SGR J1935+2154 的磁星发射的 X 射线暴有关——揭示了 FRB 的多波长对应物的第一个案例。在各种 FRB 模型中都提出了伴随或跟随 FRB 的其他波长的对应物，以及与 FRB 引擎的祖先相关的明亮发射，但到目前为止还没有进行稳健的检测。一般来说，我们所知道的 FRB 不是首选的 multimessenger 发射器。尽管如此，文献中已经讨论了可能与 FRB 或类似 FRB 事件相关的中微子和引力波发射信号。在这里，我回顾了 FRB 或类似 FRB 事件的这些建议的多波长和多信使对应物，以及搜索这些信号的观测进展。主题包括磁源模型框架内 FRB 的多波长（X 射线、γ射线、光学）发射和中微子发射，以及与引力波相关的可能的类似 FRB 的事件。
