即将到来的激光干涉仪空间天线（丽莎）对超大质量和中等质量黑洞引力波的可观测性，以及我们可以从观测中学习的物理学，将取决于两个基本因素：在丽莎最佳灵敏度窗口中发生的大质量黑洞合并的事件率和我们对引力波形的理论知识。我们首先提供了一个简洁的回顾文献的大规模黑洞合并的丽莎事件率，预测不同的形成方案。然后，我们讨论什么（在我们看来）是最紧迫的问题，以解决在波形建模。对于大质量黑洞双星的内旋，这些理论包括自旋进动、偏心率、高阶后牛顿项对振幅和相位的影响以及对内旋到坍缩的精确预测。对于黑洞衰荡，最终需要数值相对论来确定相对准正规模激发，并在匹配滤波中降低模板空间的维数。
The observability of gravitational waves from supermassive and intermediate-mass black holes by the forthcoming Laser Interferometer Space Antenna (LISA), and the physics we can learn from the observations, will depend on two basic factors: the event rates for massive black hole mergers occurring in the LISA best sensitivity window and our theoretical knowledge of the gravitational waveforms. We first provide a concise review of the literature on LISA event rates for massive black hole mergers, as predicted by different formation scenarios. Then we discuss what (in our view) are the most urgent issues to address in terms of waveform modelling. For massive black hole binary inspiral, these include spin precession, eccentricity, the effect of high-order post-Newtonian terms in the amplitude and phase and an accurate prediction of the transition from inspiral to plunge. For black hole ringdown, numerical relativity will ultimately be required to determine the relative quasinormal mode excitation and to reduce the dimensionality of the template space in matched filtering.
