论文摘要
活性银河系核（AGN）在其宿主星系上的反馈，以能够淬灭恒星形成的气体流出的形式，被认为是星系进化的主要参与者。但是，仍然缺少明确的观察性证据。测量流出属性的不确定性可能是部分原因，因为它们在与模型的比较和约束流出对星系的影响方面具有关键作用。在这里，我们简要回顾了测量流出物理特性的挑战，并概述了从高红移到低红移的流出研究。最后，我们通过VLT/Muse对Magnum对附近AGN的调查提出了亮点，那里的高内在空间分辨率（降至$ \ sim $ 10 $ 10）使我们能够准确测量电离气体外流的物理和运动性能。
Feedback from active galactic nuclei (AGN) on their host galaxies, in the form of gas outflows capable of quenching star formation, is considered a major player in galaxy evolution. However, clear observational evidence of such major impact is still missing; uncertainties in measuring outflow properties might be partly responsible because of their critical role in comparisons with models and in constraining the impact of outflows on galaxies. Here we briefly review the challenges in measuring outflow physical properties and present an overview of outflow studies from high to low redshift. Finally, we present highlights from our MAGNUM survey of nearby AGN with VLT/MUSE, where the high intrinsic spatial resolution (down to $\sim$10 pc) allows us to accurately measure the physical and kinematic properties of ionised gas outflows.
