论文摘要
近年来，引力波天文学的快速发展为黑洞光谱迅速发展的道路铺平了道路，这增强了通过其准模式（QNM）测试黑洞的可能性。在本文中，研究了轴向重力扰动和杂交公制重力重力（HMPG）中黑洞的QNM频率。 HMPG理论的特征是动态标量的自由度，并能够解释宇宙的后期加速膨胀，而无需引入任何\ textit {adhoc}筛选机制以在太阳系规模上保留动力学。我们获得了管理HMPG黑洞的轴向重力扰动并计算QNM频率的主方程。此外，在对黑洞及其QNM的审查中，我们根据牛顿后分析考虑了模型参数的约束，并显示了HMPG黑洞的QNM频率如何在观察性一致的参数空间范围内改变。
The rapid advancement of gravitational wave astronomy in recent years has paved the way for the burgeoning development of black hole spectroscopy, which enhances the possibility of testing black holes by their quasinormal modes (QNMs). In this paper, the axial gravitational perturbations and the QNM frequencies of black holes in the hybrid metric-Palatini gravity (HMPG) are investigated. The HMPG theory is characterized by a dynamical scalar degree of freedom and is able to explain the late-time accelerating expansion of the universe without introducing any \textit{ad hoc} screening mechanism to preserve the dynamics at the Solar System scale. We obtain the master equation governing the axial gravitational perturbations of the HMPG black holes and calculate the QNM frequencies. Moreover, in the scrutiny of the black holes and their QNMs, we take into account the constraints on the model parameters based on the post-Newtonian analysis, and show how the QNM frequencies of the HMPG black holes would be altered in the observationally consistent range of parameter space.
