标题： Shadow and weak gravitational lensing of a rotating regular black hole in a non-minimally coupled Einstein-Yang-Mills theory in the presence of plasma

摘要： 该论文研究了在等离子体介质中，非最小耦合爱因斯坦-杨-米尔斯理论中的常规和旋转磁荷黑洞的零测地线。 研究了磁荷和杨-米尔斯参数对光子轨道有效势和半径的影响。 然后，我们研究了在等离子体介质存在情况下，常规和旋转磁荷黑洞的阴影以及可观测量。 等离子体介质的存在会影响常规旋转黑洞阴影的表观大小，与真空情况相比。 检查了阴影半径和变形参数与杨-米尔斯参数和等离子体参数的变化关系。 此外，还研究了在均匀等离子体介质存在下，该黑洞时空弱场近似中无质量测试粒子的偏转角。 最后，我们将得到的结果与广义相对论（GR）中的Kerr-Newman和Schwarzschild黑洞解进行了比较。 显示英文摘要

摘要： 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).
