快速射电暴(FRB)是一类高度色散且短时标的射电爆发现象,大多数定位于高银纬地区并且光变曲线呈简单的单脉冲结构.FRB在其大致毫秒量级的持续时间内可释放出的总能量约为1038-1040erg,其发生率约为103-104 Gpc-3 yr-1,远高于同样条件下伽马暴(GRB)的事件率.目前已公布超过100个FRB事件,人们构建了几十个理论模型来试图解释这类现象,如双致密星并合、致密天体的坍缩、中子星与小天体的碰撞及相互作用、磁星的巨耀发以及脉冲星的巨脉冲等.但依赖单一射电波段的观测还很难对诸多模型进行辨别,而FRB的多波段辐射很有可能对其模型及爆发机制给予有效的甄别或限制,因而多波段探测对FRB的研究至关重要....

The fast radio bursts(FRB) are a type of radio bursts with a high dispersion and short time scale. Most of them are known to be located in the high galactic latitude area and the light curve is known to be a simple single pulse structure. The total energy released by FRB is approximately 1038–1040 erg in the duration of approximately several milliseconds;and the rate of FRB is about approximately 103–104 Gpc-3 yr-1, which is much higher than that of GRB under the same condition.At present, >100 FRB events have been published, and theoretical ...
