Parametrized quasinormal modes, greybody factors and their correspondence

Antoniou, Georgios

原文摘要Abstract

We present a detailed study of quasinormal modes (QNM) and greybody factors (GBFs) in the context of the parametrized QNM framework, in which modifications to general relativity are introduced as small corrections in the potential. We deduce the QNMs' and GBFs' dependence on the order of the modifications and their polynomial power. We also test the validity of the recently proposed QNM-GBF correspondence in the parametrized QNM framework by inspecting the regime at which it breaks down.

参数化准正则模式、灰体因子及其对应关系 · 本文在参数化准正则模式框架下详细研究了准正则模式和灰体因子,推导了它们对修正阶次和多项式幂次的依赖,并检验了最近提出的QNM-GBF对应关系的有效性及其失效范围。
