重复快速射电暴中的对称破缺

Symmetry Breaking in Repeating Fast Radio Bursts

J. I. Katz

摘要:

重复的快速射电暴显示了毫秒时间尺度上的时间对称性破缺("悲伤的长号")。FRB 180916 B的重复发生在其16.3 d周期的频率依赖性阶段。一些模型预测,所有这些周期性重复FRB具有相同的符号的时间不对称性,而另一些预测,这两个符号的来源是同样丰富的。其他周期性调制的重复FRB的未来观测可以在此基础上区分模型。

英文摘要:

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.
