黑洞的准正规模（QNM）引力辐射有望在几年内被观测到。导出了QNM频率的真实的和虚部偏离理想孤立黑洞频率的微扰公式。该公式为理解黑洞周围的天体物理环境提供了一种工具，一个巨大的吸积盘，影响引力波的QNM谱。我们表明，在一个简单的模型中，扰动QNM频谱可以有有趣的功能。
Quasinormal mode (QNM) gravitational radiation from black holes is expected to be observed in a few years. A perturbative formula is derived for the shifts in both the real and the imaginary part of the QNM frequencies away from those of an idealized isolated black hole. The formulation provides a tool for understanding how the astrophysical environment surrounding a black hole, e.g., a massive accretion disk, affects the QNM spectrum of gravitational waves. We show, in a simple model, that the perturbed QNM spectrum can have interesting features.
