标题： Surprises from the spins: astrophysics and relativity with detections of spinning black-hole mergers

摘要： 测量黑洞自旋对于实现引力波天文学的潜力具有关键重要性。 在天体物理方面，自旋可能是黑洞演化过程最清晰的指示器，从而提供了一种优选的方法来区分LIGO的黑洞是如何形成的。 在相对论方面，自旋导致了独特的动力学现象（从长期 inspiral 中的进动调制到合并时的引力波反冲），这些现象包含了关于潜在天体物理过程的宝贵信息。 我将举一些例子来探索自旋动力学（相对论）与环境效应（天体物理）之间这种深刻而迷人的相互作用。 黑洞自旋确实在这两个方面都隐藏着令人惊叹的意外：形态、共振、对超新星踢力的约束、多次合并世代等等... 显示英文摘要

摘要： Measurements of black-hole spins are of crucial importance to fulfill the promise of gravitational-wave astronomy. On the astrophysics side, spins are perhaps the cleanest indicator of black-hole evolutionary processes, thus providing a preferred way to discriminate how LIGO's black holes form. On the relativity side, spins are responsible for peculiar dynamical phenomena (from precessional modulations in the long inspiral to gravitational-wave recoils at merger) which encode precious information on the underlying astrophysical processes. I present some examples to explore this deep and fascinating interplay between spin dynamics (relativity) and environmental effects (astrophysics). Black-hole spins indeed hide remarkable surprises on both fronts: morphologies, resonances, constraints on supernova kicks, multiple merger generations and more...
