论文摘要
我们分析了2型Quasar（QSO2）SDSS J094521.33+173753.2的近红外积分光谱仪（NIFS）观察结果，以研究其温暖的分子和电离气体运动学。该QSO2具有10 $^{45.7} $ erg s $^{ - 1} $的辐射光度亮度和z = 0.128的红移。 NIFS提供的K频段光谱范围为1.99-2.40 $ $ m，其中低离子化（Pa $α$和Br $δ$），高电离（[[S XI] $λ$ 1.920 $ 1.920 $μ$ M和[SI〜VI] $ 1 $λ$λ$ 1.963 $ M）和温暖的分子线（5）（5）（5）检测到1-0S（1）），使我们能够研究多相气体运动学。我们的分析揭示了在检测到的所有发射线中普通旋转的气体，并且在低电离发射线的情况下，气体也流出了气体。在核谱的情况下，直径为0.3 \ arcsec〜（686 pc）的圆形孔，可以使用单个高斯成分在最大宽度（fwhm）= 350-400 km s $ s $^$^$ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a.除$ \ sim $ \ sim $ 300 km s $^{ - 1} $的窄组件外，FWHM $ \ sim $ 800和1700 km S $^{ - 1} $的蓝色换档高斯组件。我们将蓝移的广泛组件解释为流出的气体，达到最高速度，最高为$ -840 km s $^{ - 1} $，沿东南方向（Pa $ \ sim $ \ sim $ 125 $^{\ circ} $），距离$ \ sim $ 3.4 kppc fart the nucle us the nucle us的距离。离子流出的最大质量流率为$ \ dot {\ text {m}} _ {\ text {of text {out，max}} $ = 42-51 m $ _ \ odot $ yr $^{ - 1} $，其动力代表0.1 $ \％$ \％的Quasar bolinsosity。
We analyze Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2 quasar (QSO2) SDSS J094521.33+173753.2 to investigate its warm molecular and ionized gas kinematics. 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 $μ$m where low-ionization (Pa$α$ and Br$δ$), high ionization ([S XI]$λ$1.920 $μ$m and [Si~VI]$λ$1.963 $μ$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$α$, Br$δ$, 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.
