论文摘要
与铁线相关的混响是电晕的直接光子与反射的光子之间的时间滞后。所得线频谱称为2D传输函数。 2D传递函数的形状由时空的几何形状和BH的性质确定。在论文（EPJC 76：290，2016中的Ghasemi-Nodehi和Bambi）中，作者提出了参数化。该参数化旨在测试天体物理黑洞候选物的KERR性质。在本文中，我提供了Ghasemi-Nodehi-Bambi度量标准的混响映射，以限制时空的参数。除B11外，所有参数都可以约束。参数B4也很难约束。
The reverberation associated with the iron line is the time lag between direct photons from the corona and the photons reflected from the disk. The resulting line spectrum is called the 2D transfer function. The shape of the 2D transfer function is determined by the geometry of spacetime and the properties of BH. In a paper (Ghasemi-Nodehi and Bambi in EPJC 76:290, 2016), the authors have proposed a parametrization. This parametrization is aimed to test the Kerr nature of astrophysical black hole candidates. In this paper, I provide a reverberation mapping of the Ghasemi-Nodehi-Bambi metric in order to constrain the parameter of spacetime. All parameters can be constrained with the exception of b11. The parameter b4 is harder to constrain too.
