In this paper, we revisit the rotating global monopole metric and extend the metric to a rotating dyonic global monopole in the presence of a perfect fluid. We then show that the surface topology at the event horizon, related to the metric computed, is a 2-sphere using the Gauss-Bonnet theorem. By choosing $\omega =-1/3,0,1/3$ we investigate the effect of dark matter, dust and radiation on the silhouette of a black hole. The presence of the global monopole parameter $\gamma$ and the perfect fluid parameters $\upsilon$ also deform the shape of a black hole’s shadow, which has been depicted through graphical illustrations. Finally, we analyse the energy emission rate of a rotating dyonic global monopole surrounded by perfect fluid with respect to parameters.

具有整体单极子的旋转强子黑洞被完美流体包围的阴影图像

在本文中，我们将回顾旋转的整体单极子度量，并在存在理想流体的情况下将该度量扩展到旋转的重音全局单极子。然后，我们使用高斯-邦纳定理证明，与计算的度量相关的事件视界处的表面拓扑是2球面。通过选择 $\omega =-\mathrm{1个}/3，0，\mathrm{1个}/3$ 我们研究了暗物质，灰尘和辐射对黑洞轮廓的影响。整体单极子参数的存在 $\gamma$ 以及完美的流体参数 $\upsilon$ 还会使黑洞阴影的形状变形（已通过图形插图进行了描绘）。最后，就参数而言，我们分析了被理想流体包围的旋转重音全局单极子的能量发射率。
