论文摘要
在本文中,在血浆培养基中研究了重新归一化组改进(RGI)Schwarzschild黑洞(BH)的光学性质。从等离子体介质中的运动方程式开始,我们展示了如何修改RGI黑洞的阴影半径。为此,我们计算了用于均匀和非均匀等离子体介质的弱重力状态中光的偏转角。重要的是,由于血浆介质,我们发现必须修改从辐射和插入/休息气中获得的光的运动方程。反过来,这改变并修改了观察到的强度远离黑洞的表达。最后,我们为不同的等离子体模型获得了RGI黑洞的阴影图像。即使是思考,量子效应都会改变背景几何形状,这些效果也很小,实际上,使用超质量黑洞阴影通过当前技术来检测它们。参数$ω$编码量子效应,原则上,人们期望这种量子效应仅对非常小的黑洞起重要作用。另一方面,血浆介质的效果可以在黑洞的光学外观上起重要作用,因为它们会效应并修改运动方程。
In this paper, optical properties of renormalization group improved (RGI) Schwarzschild black hole (BH) are investigated in plasma medium. Starting from the equations of motions in plasma medium, we have shown how the shadow radius of the RGI black hole is modified. To this end, we have computed the deflection angle of light in the weak gravity regime for uniform and non-uniform plasma medium. Importantly, due to the plasma medium, we find that the equations of motions for light obtained from the radiating and infalling/rest gas has to be modified. This in turn, changes and modifies the expression for the intensity observed far away from the black hole. Finally, we have obtained the shadow images for the RGI black hole for different plasma models. Even thought, quantum effect changes the background geometry, these effects are very small and, practically, it is impossible to detect them with the present technology using the supermassive black hole shadows. The parameter $Ω$ encodes the quantum effects and, in principle, one expects such quantum effects to play a significant role only for very small black holes. On the other hand, the effect of plasma medium can play important role on the optical appearance of black holes since they effect and modify the equations of motions.
