本文给出了六历元甚长基线阵列(VLBA)对3C66A的观测结果。在多个频率(2.3、8.4和22.2 GHz)同时获得的高分辨率甚长基线干涉仪(VLBI)图使我们能够识别出与核心最明亮的致密组件。我们发现,堆芯的光谱可以用同步加速器自吸收模型进行合理的拟合。我们的VLBA图显示,3C66A的喷流在距核约1.2和4ms处有两次弯曲。我们还通过分析急流的自身运动,给出了我们的急流分量与以前VLBA观测中的急流分量的可能的辨别。我们发现,在六个历元的不同频率之间,从一个分量到核心的位置存在一致的差异。
We present the results of six-epoch Very Long Baseline Array (VLBA) observations of 3C 66A. The high-resolution Very Long Baseline Interferometer (VLBI) maps obtained at multi-frequency (2.3, 8.4, and 22.2 GHz) simultaneously enabled us to identify the brightest compact component with the core. We find that the spectrum of the core can be reasonably fitted by the synchrotron self-absorption model. Our VLBA maps show that the jet of 3C 66A has two bendings at about 1.2 and 4 mas from the core. We also give possible identifications of our jet components with the components in previous VLBA observations by analysing their proper motions. We find consistent differences of the position from the core in one component between different frequencies at six epochs.
