From the spectral analysis of long Suzaku observations of five radio-loud
AGNs we have been able to discover the presence of ultra-fast outflows with
velocities ~0.1c in three of them, namely 3C 111, 3C 120 and 3C 390.3. They are
consistent with being accretion disk winds/outflows. We also performed a
follow-up on 3C 111 to monitor its outflow on ~7days time-scales and detected
an anti-correlated variability of a possible relativistic emission line with
respect to blue-shifted Fe K features, following a flux increase. This provides
the first direct evidence for an accretion disk-wind connection in an AGN. The
mass outflow rate of these outflows can be comparable to the accretion rate and
their mechanical power can correspond to a significant fraction of the
bolometric luminosity and is comparable to their typical jet power. Therefore,
they can possibly play a significant role in the expected feedback from AGNs
and can give us further clues on the relation between the accretion disk and
the formation of winds/jets.
