	abstract = {Although now routinely incorporated into hydrodynamic simulations of 
galaxy evolution, the true importance of the feedback effect of the
outflows driven by active galactic nuclei (AGN) remains uncertain from
an observational perspective. This is due to a lack of accurate
information on the densities, radial scales and level of dust extinction
of the outflow regions. Here we use the unique capabilities of
VLT/Xshooter to investigate the warm outflows in a representative sample
of 9 local (0.06 \${\textless}\$ z \${\textless}\$ 0.15) ULIRGs with AGN nuclei and, for
the first time, accurately quantify the key outflow properties. We find
that the outflows are compact (0.05 \${\textless}\$ R\$\_\{[OIII]\}\$ \${\textless}\$ 1.2 kpc),
significantly reddened (median E(B-V)\${\textbackslash}sim\$0.5 magnitudes), and have
relatively high electron densities (3.4 \${\textless}\$ log\$\_\{10\}\$ n\$\_e\$
(cm\${\textasciicircum}\{-3\}\$) \${\textless}\$ 4.8). It is notable that the latter densities --
obtained using trans-auroral [SII] and [OII] emission-line ratios --
exceed those typically assumed for the warm, emission-line outflows in
active galaxies, but are similar to those estimated for broad and narrow
absorption line outflow systems detected in some type 1 AGN. Even if we
make the most optimistic assumptions about the true (deprojected)
outflow velocities, we find relatively modest mass outflow rates (\$0.07
{\textless} {\textbackslash}dot\{M\} {\textless} 11\$ M\$\_\{sol\}\$ yr\${\textasciicircum}\{-1\}\$) and kinetic powers measured
as a fraction of the AGN bolometric luminosities (\$4{\textbackslash}times10{\textasciicircum}\{-4\} {\textless}
{\textbackslash}dot\{E\}/L\_\{BOL\} {\textless}1\$\%). Therefore, although warm, AGN-driven outflows
have the potential to strongly affect the star formation histories in
the inner bulge regions (\$r {\textbackslash}sim\$ 1kpc) of nearby ULIRGs, we lack
evidence that they have a significant impact on the evolution of these
rapidly evolving systems on larger scales.},
