Q: What is the origin of the
flow?
A: The flow is launched from ~pc scales
and is
not related to the inner accretion disk. It
is energy
driven and radiation pressure force is negligible.
Possible association with the torus or the central
star cluster (proxy for SFR in the inner pc of AGN?)
Q: Is the mass loss rate
appreciable?
A: Yes, it is of order of, and sometimes
larger than
the mass accretion rate (implications for fueling?).
Q: Is the kinetic luminosity
substantial?
A: No, it is of order 0.1% of the
bolometric, cf. 5%
adopted by Di Matteo et al. 2005 (can feedback be
accounted for by high velocity flows?)
