Query: Coexistence of a non thermal jet and a complex ultra fast X-ray outflow
  in a moderately luminous AGN   Context: Recent XMM-Newton observations have revealed that IRAS 17020+4544 is
a very unusual example of black hole wind-produced feedback by a moderately
luminous AGN in a spiral galaxy. Aims: Since the source is known for being a
radio emitter, we investigated about the presence and the properties of a
non-thermal component. Methods: We observed IRAS 17020+4544 with the Very Long
Baseline Array at 5, 8, 15, and 24 GHz within a month of the 2014 XMM-Newton
observations. We further analysed archival data taken in 2000 and 2012.
Results: We detect the source at 5 GHz and on short baselines at 8 GHz. At 15
and 24 GHz, the source is below our baseline sensitivity for fringe fitting,
indicating the lack of prominent compact features. The morphology is that of an
asymmetric double, with significant diffuse emission. The spectrum between 5
and 8 GHz is rather steep ($S(\nu)\sim\nu^{-(1.0\pm0.2)}$). Our re-analysis of
the archival data at 5 and 8 GHz provides results consistent with the new
observations, suggesting that flux density and structural variability are not
important in this source. We put a limit on the separation speed between the
main components of $<0.06c$. Conclusions: IRAS 17020+4544 shows interesting
features of several classes of objects: its properties are typical of compact
steep spectrum sources, low power compact sources, radio-emitting narrow line
Seyfert 1 galaxies. However, it can not be classified in any of these
categories, remaining so far a one-of-a-kind object.
