空间引力波探测器探测EMRI系统中心目标异常反射的有效方法
Efficient search method of anomalous reflection by the central object in an EMRI system by future space gravitational wave detectors
摘要：
在我们以前的工作中，我们研究了黑洞事件视界附近的假设反射边界对极端质量比吸气（EMRI）波形的影响。即使反射效率不是非常高，我们发现可以预期波形的显著修改。那么，问题是如何在未来空间引力波天线（如LISA）的实际数据分析中实现对该特征的搜索。在本文中，我们提出了一个简单而有效的方法来检测的反射边界的签名。反射边界对EMRI轨道演化的影响的一个有趣的特征是能量和角动量损失率在频域中周期性地振荡。振荡周期对应于引力波在假设边界和角动量势垒之间往返的逆时标。我们将表明，这种独特的功能允许检测的反射边界的签名，而无需太多额外的计算成本。
英文摘要：
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.
