论文摘要
重力波迅速成为测试重力理论的非常可靠的工具。特别是，在黑洞环路阶段，重力波发射中的特征是黑洞外的时空的直接探针。在本文中，我们考虑了无幽灵的大型重力中的黑洞。这些黑洞通常具有标量头发。我们发现，引力扰动和这种标量头发之间的简单耦合可以改变黑洞的准环，尤其是在发射的引力波中产生回声。这一发现提供了一种使用重力波观测来检验大量重力理论的明确方法。
Gravitational waves are rapidly becoming a very reliable tool for testing alternative theories of gravity. In particular, features in the gravitational wave emission during black hole ringdown phase provide a direct probe of the spacetime outside the black hole. In this article, we consider black holes in ghost-free massive gravity. These black holes generically have scalar hair. We found that a simple coupling between gravitational perturbations and this scalar hair can change the quasinormal ringing of the black hole, and in particular, produce echoes in the emitted gravitational waves. This finding provides a clear-cut way to test massive gravity theory using gravitational wave observations.
