吸收暗能量的黑洞的准正规模

Quasinormal modes of black holes absorbing dark energy

Xi He, Bin Wang, Shao-Feng Wu, Chi-Yong Lin

摘要:

我们研究了吸收暗能量的黑洞的扰动。由于暗能量的吸积,黑洞的质量发生了变化。我们观察到不同形式的暗能量吸收到黑洞不同的扰动行为。这提供了提取信息的可能性,无论暗能量位于宇宙学常数边界$w=-1$之上或之下。特别地,我们发现在后期的时间尾分析,不同于其他的暗能量模型,幻影能量的吸积表现出一个增长模式中的微扰尾部。在这项工作中发现的不稳定行为与大撕裂场景是一致的,在大撕裂场景中,所有的束缚对象都被撕裂,并存在幽灵暗能量。

英文摘要:

We study perturbations of black holes absorbing dark energy. Due to the accretion of dark energy, the black hole mass changes. We observe distinct perturbation behaviors for absorption of different forms of dark energy into the black holes. This provides the possibility of extracting information whether dark energy lies above or below the cosmological constant boundary $w=-1$. In particular, we find in the late time tail analysis that, differently from the other dark energy models, the accretion of phantom energy exhibits a growing mode in the perturbation tail. The instability behavior found in this work is consistent with the Big Rip scenario, in which all of the bound objects are torn apart with the presence of the phantom dark energy.
