Query: A near-infrared study of the multi-phase outflow in the type-2 quasar
  J1509+0434   Based on new near-infrared spectroscopic data from the instrument EMIR on the
10.4 m Gran Telescopio Canarias (GTC) we report the presence of an ionized and
warm molecular outflow in the luminous type-2 quasar J150904.22+043441.8 (z =
0.1118). The ionized outflow is faster than its molecular counterpart, although
the outflow sizes that we derive for them are consistent within the errors
(1.34$\pm$0.18 kpc and 1.46$\pm$0.20 kpc respectively). We use these radii, the
broad emission-line luminosities and in the case of the ionized outflow, the
density calculated from the trans-auroral [OII] and [SII] lines, to derive mass
outflow rates and kinetic coupling efficiencies. Whilst the ionized and warm
molecular outflows represent a small fraction of the AGN power ($\leq$0.033%
and 0.0001% of L$_{bol}$ respectively), the total molecular outflow, whose mass
is estimated from an assumed warm-to-cold gas mass ratio of 6$\times10^{-5}$,
has a kinetic coupling efficiency of $\sim$1.7%L$_{bol}$. Despite the large
uncertainty, this molecular outflow represents a significant fraction of
L$_{bol}$ and it could potentially have a significant impact on the host
galaxy. In addition, the quasar spectrum reveals bright and patchy narrow
Pa$\alpha$ emission extending out to 4 arcsec (8 kpc) South-East and North-West
from the active nucleus.
