Jet-induced feedback in the [O III] lines of early evolution stage
  active galactic nuclei
  It is well known that active galactic nuclei (AGN) show various forms of
interaction with their host galaxy, in a number of phenomena generally called
AGN feedback. In particular, the relativistic plasma jets launched by a
fraction of AGN can strongly affect their environment. We present here a study
of the [O III] $\lambda\lambda$4959,5007 lines in a diverse sample of early
evolution stage AGN -- specifically narrow-line Seyfert 1 galaxies. Radio
imaging observations of all of the sources enable a division to jetted and
non-jetted sources, and exploiting this we show that the ionized gas properties
are significantly influenced by the presence of the jets, as we often find the
[O III] lines (blue-)shifted with respect to their restframe wavelength. We
also show how the radio morphology and the radio spectral index do not seem to
play a role in the origin of the [O III] shifts, thus suggesting that the
source inclination is not relevant to the lines displacement. We do not find a
strong relation between the [O III] line properties and the bolometric
luminosity, suggesting that within our sample radiatively driven outflows do
not seem to have a significant contribution to the [O III] line kinematics. We
finally suggest that [O~ III] shifts may be a good proxy to identify the
presence of relativistic jets. Additional studies, especially with
integral-field spectroscopy, will provide a deeper insight into the relation
between jets and their environment in early evolution stage AGN.
