引力光谱——从双黑洞合并的衰荡信号中测量黑洞的准正规模式——是在强场、大曲率范围内测试引力的最有前途的工具之一，但如果不了解修正引力理论特定情况下的黑洞准正规模式，则只能进行广义相对论的零测试。更具体地说，我们需要知道旋转黑洞的模式，因为典型的紧凑双星合并会导致黑洞具有大自旋。在本文中，我们首次在修正的引力理论中计算旋转黑洞的引力准正常模式，直至自旋的一阶。我们考虑爱因斯坦膨胀高斯博内引力，这是大曲率范围内广义相对论最简单的修改之一。我们发现，由于广义相对论修正而引起的模式频率和阻尼时间的变化会因旋转而显着放大。
Gravitational spectroscopy - the measurement of the quasi-normal modes of a black hole from the ringdown signal of a binary black hole coalescence - is one of the most promising tools to test gravity in the strong-field, large-curvature regime, but without the knowledge of the black hole quasi-normal modes in specific cases of modified gravity theories, only null tests of general relativity are possible. More specifically, we need to know the modes of rotating black holes, because typical compact binary mergers lead to black holes with large spins. In this article we compute, for the first time, the gravitational quasi-normal modes of rotating black holes in a modified gravity theory, up to first order in the spin. We consider Einstein-dilaton Gauss-Bonnet gravity, one of the simplest modifications of general relativity in the large-curvature regime. We find that the shifts in the mode frequencies and damping times due to general relativity modifications are significantly magnified by rotation.
