论文摘要
关于活性银河核（AGN）的反馈是否可以有效地调节其宿主星系中的恒星形成活性，存在着持续的争论。为了调查AGN驱动的流出的反馈效果，我们执行40个中度亮度的整体场光谱观察（10 $^{41.5} $ $ $ <$ <$ <$ <$ <$ <$ <$ _ {\ rm [oiiii]; cor} $ $ 10 $ <$ 10 $^{43.1} $ erg s $^$^$ n 0.集成[OIII]运动学中的流出签名。基于恒星速度分散的归一化[OIII]速度分散的径向曲线，我们测量了运动学流出尺寸，并将Kinematic的流出尺寸左度关系扩展到Kang＆Woo（2018）中报道的运动流出尺寸 - 亮度关系（2018年）中的亮度范围较大（超过[OIII III] Luminii luminii] Luminii luminiy]。运动学流出尺寸左度关系的浅坡度表明，虽然电离光子可以进一步传达，但由于各种效应，动能传递效率要降低，这表明运动学分析在量化流出尺寸和能量学方面的重要性。通过将流出运动学与宿主星系性能进行比较，我们发现具有强大流出的AGN具有较高的恒星形成速率，而与流出较弱的AGN相比。这些结果表明，当前来自AGN驱动的流出的反馈不会立即抑制或淬灭宿主星系中的恒星形成，同时其效果延迟。
There is an ongoing debate on whether feedback from active galactic nuclei (AGNs) can effectively regulate the star formation activities in their host galaxies. To investigate the feedback effect of AGN-driven outflows, we perform integral-field spectroscopic observations of 40 moderate-luminosity (10$^{41.5}$ $<$ L$_{\rm [OIII];cor}$ $<$ 10$^{43.1}$ erg s$^{-1}$) Type-2 AGNs at z $<$ 0.1, which present strong outflow signatures in the integrated [OIII] kinematics. Based on the radial profile of the normalized [OIII] velocity dispersion by stellar velocity dispersion, we measure the kinematic outflow size and extend the kinematic outflow size-luminosity relation reported in Kang & Woo (2018) into a wider luminosity range (over four orders of magnitude in [OIII] luminosity). The shallow slope of the kinematic outflow size-luminosity relation indicates that while ionizing photons can reach out further, kinetic energy transfer is much less efficient due to various effects, demonstrating the importance of kinematical analysis in quantifying the outflow size and energetics. By comparing the outflow kinematics with the host galaxy properties, we find that AGNs with strong outflows have higher star formation rate and higher HI gas fraction than those AGNs with weak outflows. These results suggest that the current feedback from AGN-driven outflows do not instantaneously suppress or quench the star formation in the host galaxies while its effect is delayed.
