关于活动星系核驱动的温暖流出的性质及其对星系演化的影响仍然存在相当大的不确定性。这是因为在地面观测中流出通常无法解决。作为研究本地宇宙中一些发展最快的星系中 AGN 外流的项目的一部分,我们在这里展示了哈勃太空望远镜 (HST)/太空望远镜成像摄谱仪 (STIS) 对 F14394+5332E 的观测结果,首次解析了超亮红外星系中的亚 kpc 热外流。观测结果揭示了一个紧凑的高电离流出区域(rmax∼0.9 kpc),设置在一个更广泛的(rmax∼1.4 kpc)光晕中,该光晕在运动学上是静止的并且具有较低的电离态。在整个流出区域测量到较大的线宽(600 < FWHM < 1500 km s−1),流出气体在半径范围内呈现出陡峭的速度梯度,蓝移速度的幅度从流出内部到外部从∼500增加到1800 km s−1。我们根据稠密云层被活动星系核驱动的热、低密度风扫过时的局部加速度和流体动力学破坏来解释观测结果。我们讨论了测量此类物体中活动星系核驱动的流出的质量流出速率和动能的含义。
Considerable uncertainties remain about the nature of warm, AGN-driven outflows and their impact on the evolution of galaxies. This is because the outflows are often unresolved in ground-based observations. As part of a project to study the AGN outflows in some of the most rapidly evolving galaxies in the local Universe, here we presentHubble Space Telescope (HST)/Space Telescope Imaging Spectrograph(STIS) observations of F14394+5332E that resolve the sub-kpc warm outflow for the first time in an ultra-luminous infrared galaxy. The observations reveal a compact, high-ionization outflow region (rmax∼ 0.9 kpc) set in a more extensive (rmax∼ 1.4 kpc) halo that is kinematically quiescent and has a lower ionization state. A large line width (600 < FWHM < 1500 km s−1) is measured throughout the outflow region, and the outflowing gas shows a steep velocity gradient with radius, with the magnitude of the blueshifted velocities increasing from ∼500 to 1800 km s−1from the inner to the outer part of the outflow. We interpret the observations in terms of the local acceleration, and hydrodynamic destruction, of dense clouds as they are swept up in a hot, low-density wind driven by the AGN. We discuss the implications for measuring the mass outflow rates and kinetic powers for the AGN-driven outflows in such objects.
