| Abstract | We present the results from the first simultaneous multi-frequency (2.3, 5.0, 8.4 and 15 GHz) Very Long Baseline Interferometry (VLBI) observations of a compact steep spectrum source 3C138. For the first time, the spectral distribution of the components within its central core region was obtained. This enables us to clearly identify the component at the western end as the location of the nuclear activity. The new measurements further clarify the superluminal motions of its inner jet components. 2004 IEEE. |
