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

摘要： 本文在爱因斯坦-高斯-博内理论框架下探讨了具有两个标量场的时变黑洞，研究了引力波（GW）的传播。 在重构模型中，鬼态频繁出现，但可以通过应用某些约束条件来消除。 我们通过检查高频率引力波在传播过程中高斯-博内耦合变化的影响来研究其行为。 在黑洞形成过程中，耦合改变了传输速度。 与离开黑洞时相比，引力波进入黑洞时的速度会发生变化。 显示英文摘要

摘要： This paper explores time-varying black holes within the framework of the Einstein-Gauss-Bonnet theory with two scalar fields, examining the propagation of gravitational waves (GW). In reconstructed models, ghosts frequently emerge but can be eliminated by applying certain 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 transmission is altered by the coupling in the creation of black holes. The speed of gravitational waves varies as they enter a black hole compared to when they exit.
