论文摘要
超级黑洞的能量反馈会影响星系中心的恒星形成。可以通过将紫外线成像和光学整合场单位数据组合来搜索星系中的活性银河核（AGN）影响恒星形成的观察证据。紫外线直接追踪近期的恒星形成，整体场单元数据可以揭示来自星系磁盘中央区域的灰尘衰减，气体电离机理和气体运动学。一项对NGC 3982的试点研究显示了银河系中央区域中的恒星形成抑制，这可能是由于AGN负反馈和外部区域的恒星形成增强所致。 NGC 3982的案例可能是在Seyfert Galaxy中运行的AGN反馈的观察证据。
The energetic feedback from supermassive black holes can influence star formation at the centres of galaxies. Observational evidence for active galactic nucleus (AGN) impact on star formation can be searched for in galaxies by combining ultraviolet imaging and optical integral field unit data. The ultraviolet flux directly traces recent star formation, and the integral field unit data can reveal dust attenuation, gas ionisation mechanisms, and gas kinematics from the central regions of the galaxy disk. A pilot study on NGC 3982 shows star formation suppression in the central regions of the galaxy, likely due to negative AGN feedback, and enhanced star formation in the outer regions. The case of NGC 3982 could be observational evidence of AGN feedback operating in a Seyfert galaxy.
