Dynamical Chern-Simons gravity cannot be strongly constrained with current experiments because it reduces to general relativity in the weak-field limit. This theory, however, introduces modifications in the nonlinear, dynamical regime, and thus it could be greatly constrained with gravitational waves from the late inspiral of black-hole binaries. We complete the first self-consistent calculation of such gravitational waves in this theory. For favorable spin orientations, advanced ground-based detectors may improve existing solar system constraints by 6 orders of magnitude.
动态陈-西蒙斯引力目前无法通过实验进行严格限制，因为它在弱场极限下会退化为广义相对论。然而，该理论在非线性动力学状态下会引入修正，因此可以通过黑洞双星的后期进动产生的引力波来对其进行严格限制。我们在该理论中首次完成了对这种引力波的自洽计算。对于有利的自旋方向，先进的地面探测器可能会将现有的太阳系限制提高 6 个数量级。
