论文摘要
使用诸如激光干涉仪空间天线（LISA）之类的空间重力波检测器（LISA），可以观察到中间质量比的灵感质量比率（IMRIS）。为此，必须对此类系统的环境影响进行建模和理解。这些效果可能包括（Baryonic）积聚磁盘和暗物质（DM）过度，所谓的尖峰。我们第一次使用具有积聚磁盘和DM尖峰的IMRI系统对IMRI系统进行建模，并比较它们对Inspiral和发射引力波信号的影响。我们研究了偏心率的演变，采用制动指数并得出了Dephasing索引，事实证明这是互补的观察性特征。它们使我们能够在IMRI系统中解散积聚磁盘和DM尖峰效应。
Intermediate Mass Ratio Inspirals (IMRIs) will be observable with space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA). To this end, the environmental effects in such systems have to be modeled and understood. These effects can include (baryonic) accretion disks and dark matter (DM) overdensities, so called spikes. For the first time, we model an IMRI system with both an accretion disk and a DM spike present and compare their effects on the inspiral and the emitted gravitational wave signal. We study the eccentricity evolution, employ the braking index and derive the dephasing index, which turn out to be complementary observational signatures. They allow us to disentangle the accretion disk and DM spike effects in the IMRI system.
