摘要:

射电星系3C84是伽玛射线亮活动星系核的代表,也是研究亚秒差距尺度喷流射电性质的最佳实验室之一。我们在这里讨论的过去和现在的活动的核区域内的中央1pc和亚秒差距大小的组件C1,C2和C3的属性。我们将这些结果与RadioAstron卫星在5GHz获得的高分辨率空间VLBI图像进行比较,并讨论了射电辐射与伽马射线辐射的可能相关性。

英文摘要:

The radio galaxy 3C84 is a representative of gamma-ray-bright misaligned active galactic nuclei (AGN) and one of the best laboratories to study the radio properties of subparsec scale jets. We discuss here the past and present activity of the nuclear region within the central 1pc and the properties of subparsec-sized components C1, C2 and C3. We compare these results with the high resolution space-VLBI image at 5GHz obtained with the RadioAstron satellite and we shortly discuss the possible correlation of radio emission with the gamma-ray emission.
