Probing the center of activity in a CSS superluminal source 3C138

Abstract

We present the results from the first simultaneous nnilti-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 f i t time. the spectral distribution of the components within its central core region was obtained. This enables us to clearly identify the component at the westem end as the location of the nuclear activity, The new measurements further clarify the superluminal motions of its inner jet components.

The time difference between the time when the event occurred and the time when the stock price was adjusted accordingly is known as the policy lag.…”
