The ’M•-b’ relation suggests a co-evolution of the central black hole and its host galaxy. Nearby AGN galaxies are ideal targets to test state-of-the-art dynamical models for the feeding - and thus growth - of a galaxy’s central region and black hole. We supplemented the NUGA IRAM 12CO survey of nearby AGN galaxies (D  40 Mpc) with high quality VLA HI data to study the overall gas flow from the outer disk to the center and to derive gas flow rates. These SPP-funded studies showed that the fueling of the central region is closely linked to the overall disk kinematics, AGN activity appears to occur during a special period in the life-time of a bar and circumnuclear star formation might play a critical role for preventing the fueling. Motivated by these results, we started to collect high-quality optical IFU data for two representative barred galaxies to investigate the importance of circumnuclear star formation for the fueling process (active: NGC6951, non-active: NGC5248). The aim of this project is via a in-depth study of the gaseous and stellar kinematics and distribution to understand how circumnuclear star formation proceeds and what its exact impact onto the nuclear fueling is.

‘M·-b’关系表明中央黑洞和其宿主星系是共同演化的。附近的AGN星系是测试最先进的动力学模型的理想目标，该模型用于星系中央区域和黑洞的喂养--从而增长--。我们用高质量的VLAHI数据补充了Nuga IRAM12co对附近活动星系群星系(D40MPC)的观测，以研究从外盘到中心的整体气体流动，并推导出气体流量。这些由SPP资助的研究表明，中央区域的燃料供应与整个盘面运动学密切相关，活动星系核活动似乎发生在棒状天体生命周期的一个特殊时期，核周恒星的形成可能在防止燃料供应方面发挥关键作用。在这些结果的推动下，我们开始收集两个有代表性的阻挡星系的高质量光学IFU数据，以研究环绕核恒星的形成对燃料过程的重要性(活跃：NGC6951，非活跃：NGC5248)。这个项目的目的是通过深入研究气体和恒星的运动学和分布，以了解环绕核恒星的形成是如何进行的，以及它对核燃料的确切影响是什么。
