论文摘要
重复快速无线电爆发显示在毫秒时尺度上的时间对称性破裂(“悲伤的长号”)。在天数的时间范围内,FRB 180916b的重复发生在其16.3 d期的频率阶段。一些模型预测,所有此类定期重复的FRB都具有时间不对称的相同迹象,而另一些模型则预测,这两个符号的来源同样丰富。对其他定期调制的重复FRB的未来观察可能会在此基础上区分模型。
Repeating Fast Radio Bursts show temporal symmetry breaking on millisecond time scales (the "sad trombone"). On a time scale of days the repetitions of FRB 180916B occur at frequency-dependent phases of its 16.3 d period. Some models predict that all such periodic repeating FRB have the same sign of temporal asymmetry, while others predict that sources with both signs are equally abundant. Future observations of other periodically modulated repeating FRB may distinguish among models on this basis.
