We investigate the ionized gas kinematics relationship with X-ray, radio and accreting
properties using a sample of 348 nearby (z < 0.4) SDSS-FIRST-X-ray detected AGNs. X-ray prop-
erties of our sample are obtained from XMM- Newton, Swi f t and Chandra observations. We unveil
the ionized gas outflows in our sample manifested by the non-gravitational broad component in
[O III]λ5007Å emission line profiles. From the comparison of the correlation of non-parametric
outflow velocities (i.e., the velocity width, the maximal velocity of outflow and line dispersion)
with X-ray luminosity and radio luminosity, we find that outflow velocities have similarly positive
correlations with both X-ray and radio luminosity. After correcting for the gravitational component,
we find that the [O III] velocity dispersion normalized by stellar mass also increases with both X-ray
luminosity and radio luminosity. We also find that, for a given X-ray (radio) luminosity, radio
(X-ray) luminous AGNs have higher outflow velocities than non-radio (non-X-ray) luminous AGNs.
Therefore, we find no clear preference between X-ray luminosity and radio luminosity in driving
high-velocity ionized outflows and conclude that both AGN activity and small-scale jets contribute
comparably. Moreover, there is no evidence that our obscured AGNs are preferentially associated
with higher velocity outflows. Finally, we find a turning point around log(λEdd) =-1.3 when we
explore the dependency of outflow velocity on Eddington ratio. It can be interpreted considering the
role of high radiation pressure (log(λEdd ) >-1.3) in causing drastic reduction in the covering factor
of the circumnuclear materials.
