论文摘要
我们提出了一种新型模型，可以为一类非重复的FRB提供解释 - 短（$ <1〜 \ rm {s} $），明亮（$ 0.1-1000〜 \ rm {jy} $）MHz-GHz频率无线电波。该模型具有三种成分 - 紧凑型物体，有效的磁场强度左右$ 10^{10}〜{\ rm Gauss} $，以及高频（MHz-GHz）重力波（GWS）。在共振时，当GWS穿过Gertsenshtein-Zel'Dovich效应时，GWS穿过这种紧凑物体的磁层时，就会发生从GWS到电磁波的能量转换。这种转化会在MHz-GHz范围内产生电磁波爆发，导致FRB。我们的模型具有三个关键特征：（i）预测峰值升华，（ii）可以自然解释脉冲宽度，并且（iii）FRB的相干性质。因此，我们得出的结论是，中子星/磁铁可能是FRB的祖细胞。此外，我们的模型提供了关于GWS在高频检测能力以外的GWS间接检测的新观点。因此，诸如FRB之类的瞬态事件是当前多通信天文学时代的丰富来源。
We present a novel model that may provide an interpretation for a class of non-repeating FRBs -- short ($<1~\rm{s}$), bright ($0.1 - 1000~\rm{Jy}$) bursts of MHz-GHz frequency radio waves. The model has three ingredients -- compact object, a progenitor with effective magnetic field strength around $10^{10}~{\rm Gauss}$, and high frequency (MHz-GHz) gravitational waves (GWs). At resonance, the energy conversion from GWs to electromagnetic waves occurs when GWs pass through the magnetosphere of such compact objects due to the Gertsenshtein-Zel'dovich effect. This conversion produces bursts of electromagnetic waves in the MHz-GHz range, leading to FRBs. Our model has three key features: (i) predict peak-flux, (ii) can naturally explain the pulse width, and (iii) coherent nature of FRB. We thus conclude that the neutron star/magnetar could be the progenitor of FRBs. Further, our model offers a novel perspective on the indirection detection of GWs at high-frequency beyond detection capabilities. Thus, transient events like FRBs are a rich source for the current era of multi-messenger astronomy.
