论文摘要
我们讨论了被指控的Reissner-Nordström（RN）广告Black Hole的阴影。在杀伤方程和汉密尔顿 - 雅各比方程的帮助下，我们计算了无粒子的测量方程。借助无效粒子的测量学，然后确定天体坐标（$α$，$β$）和RN ADS Black Hole的阴影半径。我们介绍了黑洞阴影的图形分析，发现阴影是一个完美的深色圆圈。还介绍了RN广告黑洞对阴影半径的电荷和宇宙常数的影响。在这方面，阴影的半径是电荷的减小函数。此外，我们研究了等离子体介质对RN ADS黑洞阴影的影响。在这里，我们发现圆形阴影半径随着血浆参数的增加而增加。此外，我们还讨论了RN ADS黑洞的能量发射速率。电荷，宇宙常数和等离子体参数等参数对能量发射速率的影响进行了图形分析。
We discuss the shadow cast by the charged Reissner-Nordström (RN) AdS black hole. With the help of Killing equation and Hamilton-Jacobi equation, we calculate the geodesic equations for null particle. With the help of geodesics of null particle, we then determine the celestial coordinates ($α$, $β$) and the shadow radius of the RN AdS black hole. We present a graphical analysis of the black hole shadow and find that shadow is a perfectly dark circle. The impacts of charge and cosmological constant of the RN AdS black hole on the radius of shadow are also presented. In this connection, radius of the shadow is a decreasing function of the charge. Furthermore, we study the effects of plasma medium on the RN AdS black hole shadow. Here, we find that radius of circular shadow increases with increasing plasma parameter. In addition, we also discuss the energy emission rate of RN AdS black hole. The effects of parameters like charge, cosmological constant and plasma parameter on energy emission rate are analyzed graphically.
