论文摘要
在本文中，我们考虑了在出生的非线性电动力学（BI）在存在的情况下，我们考虑了四维爱因斯坦 - 高斯 - 摩 - 邦纳特（4D EGB）重力的一致的Aoki-Gorji-Mukohyama理论。我们研究了这些黑洞的几个光学特征，例如阴影半径，能量发射速率和挠度角，并分析耦合常数，电荷和宇宙学常数对所考虑的光学量的影响。此外，我们还采用了阴影半径和准模式（QNM）之间的连接，并研究黑洞溶液周围的小标量扰动。我们表明，该理论参数的变化提供了有关双电荷黑洞溶液的光学特征的特定签名，因此可以通过使用天文学观察结果直接测试这种一致的Aoki-Gorji-Mukohyama 4D EGB黑洞模型。
In this paper, we consider black holes in the consistent Aoki-Gorji-Mukohyama theory of the four-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity in the presence of Born-Infeld (BI) nonlinear electrodynamics. We study several optical features of these black holes such as the shadow radius, energy emission rate and deflection angle, and analyse the effect of the coupling constants, the electric charge and cosmological constant on the considered optical quantities. Furthermore, we also employ the connection between the shadow radius and quasinormal modes (QNMs) and investigate small scalar perturbations around the black hole solution. We show that the variation of the parameters of the theory provide specific signatures on the optical features of the BI charged black hole solution, thus leading to the possibility of directly testing this consistent Aoki-Gorji-Mukohyama 4D EGB black hole model by using astrophysical observations.
