论文摘要
在这项工作中，我们研究了一类带有磁性旋转的黑洞空位的光学性质。假定所讨论的黑洞沉浸在典型场中，随后，预计所得的黑洞阴影将通过黑暗能量的存在来改变。我们研究了光子区域和黑洞阴影，尤其是它们对相关物理条件的依赖性，例如挑选性的状态参数，角动量和磁电荷的幅度。结果表明，光子区域敏感地取决于地平线结构并具有复杂的特征。此外，从静态观察者的角度来看，我们探索了一些可观察到的物品，尤其是与观察到的黑洞阴影变形相关的观察者。
In this work, we study the optical properties of a class of magnetically charged rotating black hole spacetimes. The black holes in question are assumed to be immersed in the quintessence field, and subsequently, the resulting black hole shadows are expected to be modified by the presence of the dark energy. We investigate the photon region and the black hole shadow, and in particular, their dependence on the relevant physical conditions such as the state parameter of the quintessence, the angular momentum, and the magnitude of the magnetic charge. It is shown that the photon regions sensitively depend on the horizon structure and possess intricate features. Moreover, from the viewpoint of a static observer, we explore a few observables, especially those associated with the distortion of the observed black hole shadows.
