摘要

探测到双星系统发出的引力波，为研究宇宙打开了一扇新的天文学窗口。我们描述了散射振幅应用于后闵可夫斯基展开领域的最新进展，以及有效二体引力势的提取。这里介绍的技术适用于任何有效的引力场论，而不局限于四维爱因斯坦引力。本文是主题问题“数学宇宙学的未来，第二卷”的一部分。

An S-matrix approach to gravitational-wave physics.

The detection of gravitational waves emitted by binary systems has opened a new astronomical window into the Universe. We describe recent advances in the field of scattering amplitudes applied to the post-Minkowskian expansion, and the extraction of the effective two-body gravitational potential. The techniques presented here apply to any effective field theory of gravity and are not restricted to four-dimensional Einstein gravity. This article is part of the theme issue 'The future of mathematical cosmology, Volume 2'.
