爱因斯坦-高斯-博内理论中双标量场的时间依赖黑洞与引力波

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

G. G. L. Nashed

AI总结:

本文在双标量场爱因斯坦-高斯-博内理论中研究时间依赖黑洞,通过约束消除鬼影,并发现变耦合影响引力波传播速度,进入与离开黑洞时速度不同。

摘要:

本文探讨了在具有两个标量场的爱因斯坦-高斯-博内理论框架内的时间变化黑洞,研究了引力波(GW)的传播。在重构模型中,鬼影经常出现,但可以通过施加某些约束来消除。我们通过研究传播过程中变高斯-博内耦合的影响,来探究高频引力波的行为。在黑洞形成过程中,耦合改变了传输速度。引力波进入黑洞时的速度与其离开时的速度不同。

英文摘要:

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.
