论文摘要
我们研究了M理论启发的模型中四维黑洞的阴影。我们首先检查了M2-branes对这种非旋转溶液的光学方面的影响。特别是，我们表明M2-Brane数字可以控制圆形阴影尺寸。这种几何行为被扭曲，用于旋转在某些模量空间区域中表现出心脏形状的溶液。实施旋转参数，我们分析了几何阴影变形。除其他外，我们恢复了较大的M2-Brane数字的圆形行为。在调查高能下的能量发射速率时，我们发现，在明确的近似值中，相关的峰随M2-Brane数量降低。此外，我们通过根据$ M87^\ star $观察参数来得出对M2-Brane数字的某些约束来研究特定M理论紧凑型的观测（来自事件地平线望远镜或未来设备）的可能联系。
We study the shadows of four dimensional black holes in M-theory inspired models. We first inspect the influence of M2-branes on such optical aspects for non-rotating solutions. In particular, we show that the M2-brane number can control the circular shadow size. This geometrical behavior is distorted for rotating solutions exhibiting cardioid shapes in certain moduli space regions. Implementing a rotation parameter, we analyze the geometrical shadow deformations. Among others, we recover the circular behaviors for a large M2-brane number. Investigating the energy emission rate at high energies, we find, in a well-defined approximation, that the associated peak decreases with the M2-brane number. Moreover, we investigate a possible connection with observations (from Event Horizon Telescope or future devices) from a particular M-theory compactification by deriving certain constraints on the M2-brane number in the light of the $M87^\star$ observational parameters.
