The extreme-gravity collisions between black holes allow us to probe the underlying theory of gravity. We apply the theory-agnostic inspiral-merger-ringdown consistency test to an example theory beyond general relativity for the first time. Here we focus on the string-inspired Einstein-dilaton Gauss-Bonnet gravity and modify the inspiral, ringdown, and remnant black hole properties of the gravitational waveform. We found that future multiband observations allow us to constrain the theory stronger than current observations by an order of magnitude. The formalism developed here can easily be applied to other theories.

用引力波的inspiral-merger-ringdown一致性测试探测弦引力

黑洞之间的极端引力碰撞使我们能够探索引力的基本理论。我们首次将与理论无关的 inspiral-merger-ringdown 一致性测试应用于超越广义相对论的示例理论。在这里，我们关注受弦启发的爱因斯坦-膨胀子高斯-博内引力，并修改引力波形的内旋、衰荡和残余黑洞特性。我们发现未来的多波段观测使我们能够将理论约束得比当前观测强一个数量级。这里发展的形式主义可以很容易地应用于其他理论。
