论文摘要
在旋转黑洞周围的轴突迷你簇和轴云的轴对物体通过轴 - 光子相互作用引起电磁波的参数共振。特别是，众所周知，质量大约$ 10^{-6} $ eV的轴心产生共振可能解释了观察到的快速无线电爆发（FRB）。在这里，我们认为，类似的高频引力波（我们称之为快速重力波爆发（FGB））是由轴突团队产生的，存在引力chern-simons（CS）耦合。典型的频率是轴突质量的一半，通常范围从KHz到GHz。我们还讨论了与FRB相关的次级重力生产以及轴云的可能的主机对象，例如典型质量的原始黑洞约为$ 10^{ - 5} m _ {\ odot} $。预计FGB的未来检测以及观察到的FRB将提供更多的轴突证据。
The axion objects such as axion mini-clusters and axion clouds around spinning black holes induce parametric resonances of electromagnetic waves through the axion-photon interaction. In particular, it has been known that the resonances from the axion with the mass around $10^{-6}$eV may explain the observed fast radio bursts (FRBs). Here we argue that similar bursts of high frequency gravitational waves, which we call the fast gravitational wave bursts (FGBs), are generated from axion clumps with the presence of gravitational Chern-Simons (CS) coupling. The typical frequency is half of the axion mass, which in general can range from kHz to GHz. We also discuss the secondary gravitational wave production associated with FRB, as well as the possible host objects of the axion clouds, such as primordial black holes with typical masses around $10^{-5}M_{\odot}$. Future detections of FGBs together with the observed FRBs are expected to provide more evidence for the axion.
