论文摘要
我们报告了我们的高分辨率（0.03 ARCSEC至0.07 ARCSEC）ALMA成像的ALMA成像，用于连续um和Broad Co（11-10）的RedShift $ z = 2.639 $的四倍的无线电大声击子，J0414+0534，以$ \ s = 2.639 $，以$ \ sim 340 $ GHZ，$ \ sim 340 $ gh，broad Co（11-10）。借助强烈的镜头放大倍率和Alma的高分辨率，我们成功地在类星体主机Galaxy中解决了喷气/粉尘和CO气体，均以$ \ sim 1 \，$ kpc延伸，首次以$ \ sim 50 \，$ PC的分辨率分辨率。 Continuum发射和CO（11-10）线的双峰结构都与很长的基线干涉法（VLBI）观察到的类似喷气机（$ \ sim 200 \，$ pc）的双峰结构都以$ 5 \，$ GHz和$ 8.4 \，$ 8.4 \，$ GHz。 The CO gas in the vicinity of both the eastern and western jet components at the location of $\sim 80\,$pc from the quasar core are moving at high velocities up to $\pm 600\,$$\textrm{km}\,\textrm{s}^{-1}$ relative to the core.观察到的特征显示出喷气机与星际培养基（ISM）之间强烈相互作用的明确证据。如CO线比例所示，类星体宿主星系的ISM中的高温和高密度环境也支持此结果。喷气机的小尺度，喷气主义相互作用和该来源的连续光谱分布表明我们正在观察类星体无线电活动的婴儿期。
We report our high-resolution (0.03 arcsec to 0.07 arcsec) ALMA imaging of the quadruply lensed radio-loud quasar MG\,J0414+0534 at redshift $z=2.639$ in the continuum and the broad CO(11-10) line at $\sim 340\,$GHz. With the help of strong lensing magnification and ALMA's high-resolution, we succeeded in resolving the jet/dust and CO gas in the quasar host galaxy both extending up to $\sim 1\,$kpc, with a resolution of $\sim 50\,$pc for the first time. Both the continuum emission and the CO(11-10) line have a similar bimodal structure aligned with the quasar jets ($\sim 200\,$pc) observed by Very Long Baseline Interferometry (VLBI) at $5\,$GHz and $8.4\,$GHz. The CO gas in the vicinity of both the eastern and western jet components at the location of $\sim 80\,$pc from the quasar core are moving at high velocities up to $\pm 600\,$$\textrm{km}\,\textrm{s}^{-1}$ relative to the core. The observed features show clear evidence of strong interaction between the jets and interstellar medium (ISM). High temperature and high density environments in the ISM of the quasar host galaxy, as suggested from CO line ratios, also support this result. The small scale of the jets, the jet-ISM interaction, and the continuum spectral energy distribution of this source indicate that we are watching the infancy stage of quasar radio activity.
