| Abstract: | We present an analysis of multi-epoch global VLBI observations of the Compact Symmetric Objects: 2352+495 and 0710+439 at 5 GHz. Analysis of data spread over almost two decades shows strong evidence for an increase in separation of the outer components of both sources at a rate of 0.2h−1c (for q=0.5 and H=100h km s−1Mpc−1). Dividing the overall sizes of the sources by their separation rates implies that these Compact Symmetric Objects have a kinematic age 104 years. These results (and those for other CSOs) strongly argue that CSOs are indeed very young sources that probably evolve into much larger classical doubles. |
