This QSO2 has a bolometric luminosity of 10$^{45.7}$ erg s$^{-1}$ and a redshift of z = 0.128. The K-band spectra provided by NIFS cover a range of 1.99-2.40 $\\mu$m where low-ionization (Pa$\\alpha$ and Br$\\delta$), high ionization ([S XI]$\\lambda$1.920 $\\mu$m and [Si~VI]$\\lambda$1.963 $\\mu$m) and warm molecular lines (from H$_2$ 1-0S(5) to 1-0S(1)) are detected, allowing us to study the multi-phase gas kinematics. Our analysis reveals gas in ordinary rotation in all the emission lines detected and also outflowing gas in the case of the low- and high-ionization emission lines. In the case of the nuclear spectrum, which corresponds to a circular aperture of 0.3\\arcsec~(686 pc) in diameter, the warm molecular lines can be characterized using a single Gaussian component of full width at half maximum (FWHM)= 350-400 km s$^{-1}$, while Pa$\\alpha$, Br$\\delta$, and [Si~VI] are best fitted with two blue-shifted Gaussian components of FWHM$\\sim$800 and 1700 km s$^{-1}$, in addition to a narrow component of $\\sim$300 km s$^{-1}$. We interpret the blue-shifted broad components as outflowing gas, which reaches the highest velocities, of up to $-$840 km s$^{-1}$, in the south-east direction (PA$\\sim$125$^{\\circ}$), extending up to a distance of $\\sim$3.4 kpc from the nucleus. The ionized outflow has a maximum mass outflow rate of $\\dot{\\text{{M}}}_{\\text{{out, max}}}$=42-51 M$_\\odot$ yr$^{-1}$, and its kinetic power represents 0.1$\\%$ of the quasar bolometric luminosity.", "revisions": [ { "version": "v1", "updated": "2022-06-30T15:16:32.000Z" } ], "analyses": { "keywords": [ "ionized gas kinematics", "warm molecular lines", "gaussian component", "maximum mass outflow rate", "analyze near-infrared integral field spectrograph" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
