摘要

我们计算了Weyl引力下三个致密天体背景下的大质量标量场的准正态模态和灰体因子：类schwarzschild后孔（称为Mannheim-Kazanas解）、非类schwarzschild黑洞和最近在（Jizba和Mudruňka）发现的可穿越虫洞，物理学报，110(12):124006,2024,https://doi.org/10.1103/PhysRevD.110.124006, arXiv:2409.08344 [gr-qc])。我们证明了质量场的谱在频域和时域上与无质量场的谱有质的不同。虽然质量项导致模式的寿命更长，但不能实现任意长寿命模式，称为准共振。

Long-lived quasinormal modes and gray-body factors of black holes and wormholes in dark matter inspired Weyl gravity

We calculate quasinormal modes and gray-body factors of a massive scalar field in the background of three compact objects in the Weyl gravity: Schwarzschild-like back holes, known as Mannheim–Kazanas solution, non-Schwrazschild-like black holes and traversable wormholes found recently in (Jizba and Mudruňka in Phys Rev D 110(12):124006, 2024, https://doi.org/10.1103/PhysRevD.110.124006, arXiv:2409.08344 [gr-qc]). We show that the spectrum of the massive field is qualitatively different from massless o ne both in the frequency and time domains. While the mass term leads to much longer lifetime of the modes, the arbitrarily long-lived modes, known as quasi-resonances, are not achieved.
