摘要

由高阶标量曲率修正给出的引力模型被认为会产生重要的后果。具有四阶曲率修正的爱因斯坦-贝尔-罗宾逊（EBR）引力促使萨贾迪等人利用微扰方法探索静态球对称黑洞解。在这项研究中，受他们工作的启发，我们研究了 EBR 引力中的 AdS 黑洞阴影，并展示了引力参数如何改变能量发射率。最后，我们讨论了存在等离子体时的相同问题，因为黑洞被认为是被介质包围的，而介质会改变光子的测地线。

Black hole shadows in Einstein-Bel-Robinson gravity* * Supported by the Internal Project (2023/2211) of Excellent Research of the Faculty of Science of Hradec Králové University

Gravity models given by higher-order scalar curvature corrections are believed to bear important consequences. Einstein-Bel-Robinson (EBR) gravity with quartic curvature modification motivated Sajadi et al. to explore static spherically symmetric black hole solutions using perturbative methods. In this study, inspired by their work, we investigate AdS black hole shadows in EBR gravity and demonstrate how the gravity parameter alters the energy emission rate. Finally, we address the same problem in the presence of plasma, because the black holes are thought to be surrounded by a medium that changes the geodesic of photons.
