摘要

本文研究了爱因斯坦-高斯-波奈理论框架下具有两个标量场的时间相关黑洞，并探讨了引力波（GW）的传播。在重构的模型中，经常会出现幽灵，通过施加一些约束可以消除幽灵。我们通过研究引力波传播过程中高斯-波奈耦合变化的影响来研究高频引力波的行为。在黑洞形成过程中，引力波的传播速度会因耦合而改变。引力波进入黑洞和离开黑洞时的传播速度不同。

Time dependent black holes and gravitational wave in Einstein–Gauss–Bonnet theory with two scalar fields

In this paper, we investigate the time dependent black holes in the frame of Einstein–Gauss–Bonnet theory having two scalar fields and investigate the propagation of the gravitational wave (GW). In the reconstructed models, there often appear ghosts, which could be eliminated by imposing some constraints. We investigate the behavior of high-frequency gravitational waves by examining the effects of varying Gauss–Bonnet coupling during their propagation. The speed of propagation changes due to the coupling during the black hole formation process. The propagation speed of gravitational waves differs when they enter the black hole compared to when they exit.
