单旋转Myers-Perry-de Sitter黑洞的大质量标量扰动

Massive Scalar Perturbations on Myers-Perry-de Sitter Black Holes with a Single Rotation

Supakchai Ponglertsakul, Bogeun Gwak

摘要:

本文研究了高维单旋转Myers-Perry-de Sitter(MP-dS)黑洞对标量场扰动的稳定性。讨论了具有单自旋参数的MP-dS黑洞的相空间.此外,利用渐近迭代法和六阶Wentzel-Kramers-Brillouin近似计算了MP-dS黑洞的准正规模.对于近极值MP-dS黑洞,事件视界可能相当接近宇宙学视界。在这种情况下,Pöschl-Teller技术产生一个精确的解析公式的QNM。研究发现,当黑洞的自旋参数增大时,标量微扰模的振荡频率变高,衰减变快。此外,我们还发现单旋转的MP-dS黑洞在扰动下是稳定的.

英文摘要:

This study investigates the stability of higher-dimensional singly rotating Myers-Perry-de Sitter (MP-dS) black holes against scalar field perturbations. The phase spaces of MP-dS black holes with one spin parameter are discussed. Additionally, the quasinormal modes (QNMs) of MP-dS black holes are calculated via the asymptotic iteration method and sixth-order Wentzel-Kramers-Brillouin approximation. For near-extremal MP-dS black holes, the event horizon may be considerably close to the cosmological horizon. In such cases, the Pöschl-Teller technique yields an accurate analytic formula for the QNMs. It is found that when the spin parameter of a black hole increases, the scalar perturbation modes oscillate at higher frequencies and decay faster. Furthermore, the MP-dS black hole with a single rotation is found to be stable under perturbation.
