Gravitational waves (GWs) have changed the way we explore the cosmo. They have uncovered new types of astrophysical objects (black hole binaries, black hole-neutron star binaries), which we had imagined but never seen. Thanks to GWs, we are closer than ever before to understanding the state of matter in the densest stars, the fundamental nature of gravity, the structure of our Universe.These advances, made in less then a decade with only two detectors, show GW astronomy's unique potential: the ability to probe gravity at its extreme and, at the same time, large-scale astrophysics.The goal of this project is to exploit both of GW astronomy's strengths, delivering data analysis tools, analytic results and practicalstrategies. On the fundamental side, the project will address burning questions about the final stage of the merging of two blackholes (the "ringdown"). Thanks to recent advances in perturbation theory, it is finally possible to understand - beyond leading order - how black holes settle down after a merger. This project will help fill-in one of the few missing blocks in the understanding of our century-old theory of gravity. This, together with practical strategies to distinguish new physics from old-fashioned astrophysics, will be essential to exploit near future (2023+) and future (2030s) GW observations.As an MSCA fellow, the applicant will receive crucial training in the fundamental aspects of gravity at the Nottingham Centre ofGravity (University of Nottingham). The Centre, whose expertise spans gravity, particle physics and cosmology, will be the idealenvironment for this interdisciplinary project. The project's approach draws also from the applicant's expertise in theoretical physicsand astrophysics, data analysis and numerical methods. An academic secondment at Caltech will complete the multifaceted trainingnecessary for cutting-edge GW research, and will ensure the project's impact on key stakeholders, including current GW detectors.

引力波（GWS）改变了我们探索宇宙的方式。他们发现了我们想象的但从未见过的新型天体物理物体（黑洞二进制物，黑洞中的二进制二进制物）。多亏了GWS，我们比以往任何时候都更加接近了解最密集的恒星中物质的状态，重力的基本本质，我们宇宙的结构。这些进步仅在不到十年的时间内与两个探测器一起进行，显示了GW天文学的独特潜力：极端和同一时间，大型天文学的孔子，概念的目标是孔子的范围。提供数据分析工具，分析结果和实践策略。在基本方面，该项目将解决有关两个黑洞（“戒指”）合并的最后阶段的迫切问题。得益于扰动理论的最新进展，最终有可能理解 - 超出领先的秩序 - 合并后黑洞如何安定下来。该项目将帮助填补对我们百年历史的重力理论的少数几个缺失障碍之一。这是将新物理学与老式天体物理学区分开的实用策略，对于开发不久的将来（2023+）和未来（2030年代）GW观察至关重要。作为MSCA研究员，申请人将在诺丁汉中心（Nottingham Center）的重力方面接受至关重要的培训。该中心的专业知识涵盖了重力，粒子物理和宇宙学，将成为这个跨学科项目的理想环境。该项目的方法还借鉴了申请人在理论物理和天体物理学，数据分析和数值方法方面的专业知识。加州理工学院（Caltech）的学术借调将完成多方面的培训，以实现最先进的GW研究，并确保项目对包括当前GW探测器在内的主要利益相关者的影响。
