论文摘要
在我们先前的工作中，我们研究了黑洞事件地平线附近的假设反射边界对极端质量比率灵感（EMRIS）的波形的影响。即使反射效率不是很高，我们也发现可以预期对波形进行重大修改。然后，问题是如何在未来空间引力波天线（例如丽莎）的实际数据分析中实施该签名的搜索。在本文中，我们提出了一种简单但有效的方法来检测反射边界的特征。反射边界对EMRIS轨道演化的影响的有趣特征是，能量和角动量损耗速率在频域中定期振荡。振荡周期对应于假设边界和角动量屏障之间重力波的往返时间尺度。我们将表明，这种特殊的功能允许检测反射边界的签名，而无需额外的计算成本。
In our previous work we investigated the effect of the hypothetical reflecting boundary near the black hole event horizon on the waveform from extreme mass-ratio inspirals (EMRIs). Even if the reflection efficiency is not extremely high, we found that a significant modification of the waveform can be expected. Then, the question is how to implement the search for this signature in the actual data analysis of future space gravitational wave antennas, such as LISA. In this paper we propose a simple but efficient method to detect the signature of the reflecting boundary. The interesting feature of the effect of the reflecting boundary on the orbital evolution of EMRIs is that the energy and angular momentum loss rates periodically oscillate in the frequency domain. The oscillation period is corresponding to the inverse time scale for the round trip of gravitational waves between the hypothetical boundary and the angular momentum barrier. We will show that this peculiar feature allows to detect the signature of the reflecting boundary without much additional computational cost.
