Andrzej Marecki, Peter D. Barthel, Antonis Polatidis +1
AGN with the so-called `double-double' radio structure have been interpreted as restarted AGN where the inner structure is a manifestation of a new phase of activity which happened…
Renewed Radio Activity of Age 370 years in the Extragalactic Source 0108+388
Izabela Owsianik, John E. Conway, Antonis G. Polatidis
We present the results of multi-epoch global VLBI observations of the Compact Symmetric Object (CSO) 0108+388 at 5 GHz. Analysis of data spread over 12 years shows strong evidence…
