摘要

黑洞阴影的第一幅图像为检验引力的扩展理论开辟了新的可能性。利用纽曼-詹尼斯方法，我们得到了带有量子场修正的（R + {{R}^{2}}）模型的旋转度量。我们已经证明，并非所有之前得到的解都与事件地平线望远镜的实验结果一致。因此，我们提出了基于黑洞旋转考虑的引力扩展理论的更精确的变体选择。

Extended Gravity and Black Hole Shadows: Rotation Accounting

The first images of the shadows of black holes have opened up new possibilities for testing extended theories of gravity. Using the Newman–Janis method, metrics with rotation for the \(R + {{R}^{2}}\) model with quantum field corrections are obtained. We have shown that not all previously obtained solutions are consistent with the experimental results of the Event Horizon Telescope. So the more accurate variant to select extended theories of gravity based on black hole rotation taking into account is proposed.
