摘要

我们利用詹姆斯-韦伯太空望远镜(JWST)的中红外光谱积分场单元(IFU)数据研究了Seyfert 1 NGC 7469中恒星形成与AGN之间的联系。我们利用积分场数据生成光谱中不同发射线的图谱,如恒星形成(SF)示踪线[Ne II] 12.81{\mu}m,或AGN示踪线[Ne V] 14.32{\mu}m。我们可以利用空间分辨的中红外诊断图来区分AGN主导区和SF主导区,并通过构建光离子化模型来进一步研究每个区域的电离源。我们发现,之前探测到的东风充斥着图中的一个中间区域,介于恒星形成和 AGN 象限之间。这种风还与环中[Ne II]发射的减少相吻合,这表明电离锥在这个方向上与环相交。尽管有这种 AGN 负反馈的证据,但鉴于电离锥的狭窄开口角及其方向,这不会是一个有效反馈的案例。

Core Revelations: the Star Formation and AGN Connection at the Heart of NGC 7469
We investigate the star formation-AGN connection in the Seyfert 1 NGC 7469 using James Webb Space Telescope (JWST) mid-infrared spectroscopic integral field unit (IFU) data. We use the IFU data to generate maps of different emission lines present in the spectrum, such as the star-formation (SF) tracer [Ne II] 12.81{\mu}m, or the AGN tracer [Ne V] 14.32{\mu}m. We can separate the AGN- and SF-dominated regions using spatially resolved mid-IR diagnostic diagrams, and further investigate the ionization sources powering each region by constructing photoionization models. We find that the previously detected eastern wind populates an intermediary region of the diagrams, between our star-forming and AGN quadrants. This wind also coincides with a reduction in the [Ne II] emission in the ring, which suggests that the ionization cone intersects the ring in this direction. In spite of this evidence of negative AGN feedback, given the narrow opening angle of the ionization cone and its orientation, this would not be a case of efficient feedback.
