论文摘要

我们提出了四倍镜头Z = 1.51 Quasar HS 0810+2554的Atacama大毫米/亚毫米阵列(ALMA)观察结果,这些观察结果对CO分子气体的运动学和形态提供了有用的见解,以及〜2 mm Continuum Continuum contrumation和〜2 mm cantum insus of the Quasar Host Host Host host Galaxy。 MM-Continuum和光谱集成CO(3-2)图像的透镜建模表明,MM-Continuum的源具有E〜0.9的偏心率,大小为〜1.6 kpc,线发射的源具有E 〜0.7的偏心度,其大小为〜1 kpc。 CO(2-1)和CO(3-2)线的空间整合发射显示了三个峰结构,外部峰被DV_21 = 220 +\ - 19 km S^-1和DV_32 = 245 +/- 28 +/- 28 km S^-1,表明存在旋转的分子CO线的存在,表明存在旋转的分子CO系列。高空间分辨率图像的镜头反转证实了发射气体的旋转的存在。假设Alpha_co的转化因子= 0.8 m_solar(k km s^-1 pc^2)^-1我们发现HS 0810 +2554的分子气体质量为m _ mol = [(5.2 +/-- 1.5)/mu_32] x10 x10 x10^10 m_solar,mu_32是mu_32是CO的MAGE_32 CO(3-2)。我们报告了在3.0-4.7的Sigma置信度下可能检测到的CO(3-2)发射线的CO发射的高速块发射线,速度为1702 km S^-1。我们发现,鉴于在小规模的超快流出中观察到的动量通量,大规模分子风的动量提升低于预测能量流出的值。

We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the quadruply lensed z=1.51 quasar HS 0810+2554 which provide useful insight on the kinematics and morphology of the CO molecular gas and the ~2 mm continuum emission in the quasar host galaxy. Lens modeling of the mm-continuum and the spectrally integrated CO(3-2) images indicates that the source of the mm-continuum has an eccentricity of e~0.9 with a size of ~1.6 kpc and the source of line emission has an eccentricity of e~0.7 with a size of ~1 kpc. The spatially integrated emission of the CO(2-1) and CO(3-2) lines shows a triple peak structure with the outer peaks separated by Dv_21 = 220 +\- 19 km s^-1 and Dv_32 = 245 +/- 28 km s^-1, respectively, suggesting the presence of rotating molecular CO line emitting gas. Lensing inversion of the high spatial resolution images confirms the presence of rotation of the line emitting gas. Assuming a conversion factor of alpha_CO = 0.8 M_solar (K km s^-1 pc^2)^-1 we find the molecular gas mass of HS 0810+2554 to be M _ Mol = [(5.2 +/- 1.5)/mu_32] x10^10 M_solar, where mu_32 is the magnification of the CO(3-2) emission. We report the possible detection, at the 3.0 - 4.7 sigma confidence level, of shifted CO(3-2) emission lines of high-velocity clumps of CO emission with velocities up to 1702 km s^-1. We find that the momentum boost of the large scale molecular wind is below the value predicted for an energy-conserving outflow given the momentum flux observed in the small scale ultrafast outflow.
