摘要
黑洞吸积系统中的喷流形成是一个长期存在的问题。有观点认为，喷流可通过提取黑洞的旋转能（“BZ 喷流”）或吸积流的旋转能（“盘喷流”）而形成。尽管两种模型均可产生准直的相对论性外流，但均未能成功解释观测到的喷流形态。本文通过采用广义相对论磁流体动力学模拟，并考虑由喷流扭曲不稳定性驱动的磁重联所加速的非热电子，利用辐射转移计算获得图像，并与 M87 喷流的毫米波观测进行比较。我们发现，源自高自旋黑洞周围磁囚禁盘的 BZ 喷流能够很好地再现喷流形态，包括其宽度与边缘增亮特征。

备注
We would like to submit a new article with the same research question as this article. We have made significant modifications in the following two aspects. We have constructed a more refined and accurate theoretical model and greatly improved the resolution of the simulation. Republishing a new version avoids confusion and misleading readers
