论文摘要
NGC 7469是一个众所周知的发光ir星系，周围有一个周围的Seyfert 1 AGN，上面有一个环核星形形成环（$ \ sim 830 $ PC半径）。以前在X射线和紫外线中检测到核未解决的风，以及IR冠状线的延伸双样式流出。我们通过测量$ \ mathrm {Hβ} $和[O III] $λ5007$光学排放线的运动学方法来搜索扩展流出。我们找到了两个流出运动方案的证据：一个较慢的机制延伸到大多数恒星形成环（可能是由大型恒星形成驱动的驱动）和更快的方案（最大速度为$ -715 \ \ \ \ \ \ \ \ m atrm {km \ s^{ - 1}} $），仅在[OII III]之间，在[OII III]之间，在[O III]之间。戒指，可能由AGN驱动。这项工作显示了可以有效地通过空间分辨的AGN/恒星形成反馈组合的案例，这为对AGN中央基洛帕尔萨克（Kiloparsec）的反馈过程提供了有前途的途径。
NGC 7469 is a well known Luminous IR Galaxy, with a circumnuclear star formation ring ($\sim 830$ pc radius) surrounding a Seyfert 1 AGN. Nuclear unresolved winds were previously detected in X-rays and UV, as well as an extended biconical outflow in IR coronal lines. We search for extended outflows by measuring the kinematics of the $\mathrm{Hβ}$ and [O III] $λ5007$ optical emission lines, in data of the VLT/MUSE integral field spectrograph. We find evidence of two outflow kinematic regimes: one slower regime extending across most of the star formation ring -- possibly driven by the massive star formation -- and a faster regime (with a maximum velocity of $-715 \ \mathrm{km \ s^{-1}}$), only observed in [O III], in the western region between the AGN and the massive star forming regions of the ring, likely AGN-driven. This work shows a case where combined AGN/star-formation feedback can be effectively spatially-resolved, opening up a promising path toward a deeper understanding of feedback processes in the central kiloparsec of AGN.
