【摘要】本文给出类星体3C 147的混杂图,它是应用1.662GHz VLBI技术在历元1987.85的观测结果.该致密天体是由一个未分解的核,一个延伸的不对称的喷流和一个更大的,完全分解的晕所组成.核本身向东北方向略有延伸,并指向同方向的一片低亮度区域,这点尚需进一步观测证实.更多还原

【Abstract】 We present a hybrid map of QSO 3C147. It is the result of a λ18 cm VLBI observation at epoch 1987. 85. This compact radio source consists of a unresolved core, an extended asymmetric jet and a larger, completely resolved halo. We can find that the core has a small extension to the northeast and points to a low bright area. But we have to confirm it with more VLBI observations in future.更多还原
