论文摘要
由于最近的天体物理观察，我们研究了具有宇宙常数的四个尺寸充电的黑洞的阴影行为。这项研究是根据由电荷和旋转参数参数参数的减少模量空间进行的。对于固定的观察者，我们在某些细节上分析了在反de Sitter背景中Kerr-Newman和Kerr-Sen四维黑洞的阴影行为以及相应的裸奇异点。然后，通过计算几何观测值和能量发射速率来提供比较讨论。
Motivated by recent astrophysical observations, we investigate the shadow behaviors of four dimensional charged rotating black holes with a cosmological constant. This study is made in terms of a reduced moduli space parameterized by the charge and the rotation parameters. For fixed observers, we analyse in some details the shadow behaviors and the corresponding naked singularities of Kerr-Newman and Kerr-Sen four-dimensional black holes in Anti de Sitter backgrounds. Then, a comparative discussion is provided by computing the geometrical observables and the energy emission rate.
