论文摘要
研究了由等离子介质包围的非最低耦合的爱因斯坦 - 东米尔斯理论的常规和旋转磁性黑洞的无效的黑洞。磁电荷和阳米尔斯参数对光子轨道有效势和半径的影响。然后，我们研究了等离子体介质存在的常规且旋转的磁性黑洞的阴影以及可观察物的阴影。与真空案例相比，血浆介质的存在会影响常规旋转黑洞阴影的表观大小。阴影半径的变化和变形参数与杨麦克尔和等离子体参数的变化已经检查。此外，还研究了在同质等离子体培养基存在下，该黑洞时空周围弱场近似中无质量测试颗粒的挠度角。最后，我们将获得的结果与Kerr-Newman和Schwarzschild Black Hole溶液（GR）进行了比较。
The null geodesics of the regular and rotating magnetically charged black hole in a non-minimally coupled Einstein-Yang-Mills theory surrounded by a plasma medium is studied. The effect of magnetic charge and Yang-Mills parameter on the effective potential and radius of photon orbits has investigated. We then study the shadow of a regular and rotating magnetically charged black hole along with the observables in presence of the plasma medium. The presence of plasma medium affects the apparent size of the shadow of a regular rotating black hole in comparison to vacuum case. Variation of shadow radius and deformation parameter with Yang-Mills and plasma parameter has examined. Furthermore, the deflection angle of the massless test particles in weak field approximation around this black hole spacetime in presence of homogeneous plasma medium is also investigated. Finally, we have compared the obtained results with Kerr-Newman and Schwarzschild black hole solutions in general relativity (GR).
