Renewed Radio Activity of Age 370 years in the Extragalactic Source 0108+388.


Abstract (from CDS):

We present the results of multi-epoch global VLBI observations of the Compact Symmetric Object (CSO) 0108+388 at 5GHz. Analysis of data spread over 12 years shows strong evidence for an increase in the separation of the outer components at a rate of 0.197±0.026h–1c. Given an overall size of 22.2h–1pc this implies a kinematic age of only 367±48yrs. This result strongly supports the idea that radio emission in Compact Symmetric Objects arises from recently activated radio sources. The presence of weak radio emission on kpc-scales in 0108+388 suggests recurrent activity in this source, and that we are observing it just as a new period of activity is beginning.
