Query: NuSTAR view of the black hole wind in the galaxy merger IRAS
  F11119$+$3257   Galactic winds driven by active galactic nuclei (AGN) have been invoked to
play a fundamental role in the co-evolution between supermassive black holes
and their host galaxies. Finding observational evidence of such feedback
mechanisms is of crucial importance and it requires a multi-wavelength approach
in order to compare winds at different scales and phases. In Tombesi et al.
(2015) we reported the detection of a powerful ultra-fast outflow (UFO) in the
Suzaku X-ray spectrum of the ultra-luminous infrared galaxy IRAS F11119$+$3257.
The comparison with a galaxy-scale OH molecular outflow observed with Herschel
in the same source supported the energy-conserving scenario for AGN feedback.
The main objective of this work is to perform an independent check of the
Suzaku results using the higher sensitivity and wider X-ray continuum coverage
of NuSTAR. We clearly detect a highly ionized Fe K UFO in the 100ks NuSTAR
spectrum with parameters $N_H = (3.2\pm1.5)\times 10^{24}$ cm$^{-2}$,
log$\xi$$=$$4.0^{+1.2}_{-0.3}$ erg s$^{-1}$ cm, and $v_{\text{out}} =
0.253^{+0.061}_{-0.118}$ c. The launching radius is likely at a distance of $r
\ge 16$ $r_s$ from the black hole. The mass outflow rate is in the range
$\dot{M}_{out}$$\simeq$0.5-2 $M_{\odot}$ yr$^{-1}$. The UFO momentum rate and
power are $\dot{P}_{out} \simeq$0.5-2 $L_{AGN}/c$ and $\dot{E}_{out}
\simeq$7-27\% $L_{AGN}$, respectively. The UFO parameters are consistent
between the 2013 Suzaku and the 2015 NuSTAR observations. Only the column
density is found to be variable, possibly suggesting a clumpy wind. The
comparison with the energetics of molecular outflows estimated in infrared and
millimeter wavelengths support a connection between the nuclear and
galaxy-scale winds in luminous AGN.
