标题： Shadow, deflection angle and quasinormal modes of Born-Infeld charged black holes

摘要： 本文中，我们研究了在存在Born-Infeld（BI）非线性电动力学的情况下，四维爱因斯坦-Gauss-Bonnet（4D EGB）引力的一致Aoki-Gorji-Mukohyama理论中的黑洞。 我们研究了这些黑洞的几个光学特性，例如阴影半径、能量发射率和偏转角，并分析了耦合常数、电荷和宇宙常数对所考虑的光学量的影响。 此外，我们还利用阴影半径与准正则模式（QNMs）之间的联系，研究了黑洞解周围的微小标量扰动。 我们表明，该理论参数的变化会在BI带电黑洞解的光学特征上留下特定标志，从而有可能通过天文学观测直接检验这个一致的Aoki-Gorji-Mukohyama 4D EGB黑洞模型。 显示英文摘要

摘要： 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.
