摘要
3C 84 是一个邻近的射电源，具有复杂的总强度结构，显示出线性偏振和光谱特征。对中心引擎区域的详细调查需要使用高于迄今可用的最大频率 86GHz 的甚长基线干涉测量（VLBI）。利用在最高可用频率 228GHz 下的超高分辨率 VLBI 观测，我们旨在直接探测紧凑结构并理解 3C 84 紧凑区域的物理条件。我们使用了 EHT 228GHz 观测数据，鉴于有限的 (u,v) 覆盖范围，对数据应用了几何模型拟合。我们还采用了该源 quasi-simultaneously 观测的多频率 VLBI 数据，以对核心结构进行全面分析。我们报告了在 3C 84 中心超大质量黑洞（SMBH）周围探测到一个高度有序且强大的磁场。亮度温度分析表明该系统处于能量均分状态。我们确定了转折频率为 GHz，相应的同步自吸收磁场为 G，均分磁场为 G。解析出三个分量，检测到该对象最高的分数偏振度（%）。这些分量的位置与 2017-2018 年以来低频 VLBI 观测中看到的相符。我们报告了 228GHz 处光谱的陡峭负斜率。我们利用这些发现测试了 3C 84 中喷流形成、传播和法拉第旋转的模型。我们对不同流动几何结构和黑洞自旋的调查结果支持这样一个模型：在快速旋转的超大质量黑洞周围，处于磁囚禁状态的平流主导吸积流是 3C 84 核心中喷流发射系统的模型。然而，由于有限的 (u,v) 覆盖范围导致的系统不确定性不容忽视。
