论文摘要
我们建立了一种通用的，全面的形式主义，以研究球形对称，非武器黑孔空间的极端质量比率系统的重力波排放。天体物理设置的潜在应用范围从积聚的重型物质到轴承云和暗物质环境中的物质，可以评估银河势的影响，增生，重力阻力和光晕反馈对重力波的产生和传播的影响。我们将方法应用于物质光环中的黑洞。我们发现赋予重力波信号的流体模式（黑洞基本模式不稳定性的明确证据）以及通过通过敏感的低频检测器从重力波测量中推断出银河系特性的诱人可能性。
We establish a generic, fully-relativistic formalism to study gravitational-wave emission by extreme-mass-ratio systems in spherically-symmetric, non-vacuum black-hole spacetimes. The potential applications to astrophysical setups range from black holes accreting baryonic matter to those within axionic clouds and dark matter environments, allowing to assess the impact of the galactic potential, of accretion, gravitational drag and halo feedback on the generation and propagation of gravitational-waves. We apply our methods to a black hole within a halo of matter. We find fluid modes imparted to the gravitational-wave signal (a clear evidence of the black hole fundamental mode instability) and the tantalizing possibility to infer galactic properties from gravitational-wave measurements by sensitive, low-frequency detectors.
