论文摘要
快速无线电爆发（FRB）的性质目前尚不清楚。重复FRB比非重复的FRB提供了更好的机会，因为可以确定它们的同时多波长对应物。 FRB的磁耀斑模型是最有前途的模型之一，除了无线电爆发外，还可以预测高能发射。为了调查这种可能性，我们在所有Swift/BAT事件模式数据中搜索了同时和准同时的短期硬性X射线爆发，这些数据涵盖了重复的FRB 121102中快速无线电爆发的时期，通过利用BAT的Arcmin的Arcmin Arcmin级别的空间分辨率和视野范围。我们没有发现与那些无线电爆发同时发生的任何重大硬X射线爆发。我们还调查了潜在的短X射线爆发发生了与这些无线电爆发的准平台（出现时间在数百秒至几秒钟之间的不同之处），并得出结论，即使是最好的候选者也与背景波动一致。因此，我们的调查得出的结论是，在重复的FRB 121102中，与迅速/蝙蝠的迅速X射线爆发同时或准单相中的爆发。
The nature of fast radio bursts (FRBs) is currently unknown. Repeating FRBs offer better opportunity than non-repeating FRBs since their simultaneous multi-wavelength counterparts might be identified. The magnetar flare model of FRBs is one of the most promising models which predicts high energy emission in addition to radio burst emission. To investigate such a possibility, we have searched for simultaneous and quasi-simultaneous short-term hard X-ray bursts in all the Swift/BAT event mode data which covered the periods when fast radio bursts were reported detections in the repeating FRB 121102, by making use of BAT's arcmin level spacial resolution and wide field-of-view. We did not find any significant hard X-ray bursts which occurred simultaneously to those radio bursts. We also investigated potential short X-ray bursts occurred quasi-simultaneous with those radio bursts (occurrence time differs in the range from hundreds of seconds to thousands of seconds) and concluded that even the best candidates are consistent with background fluctuations. Therefore our investigation concluded that there were no hard X-ray bursts detectable with Swift/BAT which occurred simultaneously or quasi-simultaneously with those fast radio bursts in the repeating FRB 121102.
