研究了中子星星合并前由于致密天体间磁层相互作用而产生的相干射电辐射。我们考虑了两种可能的辐射机制，并表明，如果一个中子星星的表面磁场Bs ≥ 1012 G，相干毫秒射电爆发的特征时间形态和倾角依赖性是可观察到的Gpc距离与下一代无线电设施。我们探索多信使和多波长的方法来识别NS合并起源的无线电爆发，如在快速无线电爆发调查，触发观测的伽马射线爆发和引力波事件，和光学/无线电后续的快速无线电爆发在寻找kilonova和无线电余辉发射。我们目前和未来的观测设施，我们的研究结果，并提出建议，验证或约束模型。
We investigate pre-merger coherent radio emission from neutron star mergers arising due to the magnetospheric interaction between compact objects. We consider two plausible radiation mechanisms, and show that if one neutron star has a surface magnetic field Bs ≥ 1012G, coherent millisecond radio bursts with characteristic temporal morphology and inclination angle dependence are observable to Gpc distances with next-generation radio facilities. We explore multi-messenger and multi-wavelength methods of identification of a NS merger origin of radio bursts, such as in fast radio burst surveys, triggered observations of gamma-ray bursts and gravitational wave events, and optical/radio follow-up of fast radio bursts in search of kilonova and radio afterglow emission. We present our findings for current and future observing facilities, and make recommendations for verifying or constraining the model.
