	abstract = {We have recently improved our model of active galactic nucleus (AGN) by 
attaching the supermassive black hole (SMBH) to a massive nuclear star
cluster (NSC). Here we study the effects of this new model in massive,
gas-rich galaxies with several simulations of different feedback recipes
with the hydrodynamics code RAMSES. These simulations are compared to a
reference simulation without any feedback, in which the cooling halo gas
is quickly consumed in a burst of star formation. In the presence of
strong supernovae (SN) feedback, we observe the formation of a galactic
fountain that regulates star formation over a longer period, but without
halting it. If only AGN feedback is considered, as soon as the SMBH
reaches a critical mass, strong outflows of hot gas are launched and
prevent the cooling halo gas from reaching the disk, thus efficiently
halting star formation, leading to the so-called "quenching". If both
feedback mechanisms act in tandem, we observe a non-linear coupling, in
the sense that the dense gas in the supernovae-powered galactic fountain
is propelled by the hot outflow powered by the AGN at much larger radii
than without AGN. We argue that these particular outflows are able to
unbind dense gas from the galactic halo, thanks to the combined effect
of SN and AGN feedback. We speculate that this mechanism occurs at the
end of the fast growing phase of SMBH, and is at the origin of the dense
molecular outflows observed in many massive high-redshift galaxies.},
