Structure and kinematics of AGN: The interplay between accretion disk, broad line regionand dust torus

位于波鸿、哥廷根、海法和特拉维夫的四个天文研究所在DFG资助的一个项目中合作，利用反射映射技术探索塞弗特星系和类星体的内部结构。迄今为止获得的回波映射数据超出了预期：它们可以确定外部吸积盘和内部宽线区域之间的过渡，验证宽线区域和内部尘埃环的假定碗状几何形状，并研究类星体和塞弗特星系的宇宙学相关偏差效应。除了进行新的观测外，我们还改进了数据分析算法和理论模型，这对于数据的物理解释是必要的。为了完成该计划的成功观测，并对收集的大量数据进行物理解释，我们要求将DFG的支持延长两年。保证对类星体物理学产生新的深远影响，特别是对中心区域的几何学和运动学，以及吸积盘、宽线区域和尘埃环之间的相互作用，并将在项目延长期间发表。

The four astronomical institutes in Bochum, Göttingen, Haifa and Tel-Aviv collaborate in a DFG-funded project to explore the internal structure of Seyfert galaxies and quasars using the reverberation-mapping technique. The echo-mapping data secured so far exceed the expectations: they allow to determine the transition between the outer accretion disk and the inner broad-line region, to verify the putative bowl-shaped geometry of the broad-line region and the inner dust torus, and to study cosmologically relevant bias-effects for quasars and Seyfert galaxies. Apart from performing new observations we also improved data-analysis algorithms and theoretical models, which are necessary for the physical interpretation of the data. To complete the successfully ongoing observational aspects of the program, and physically interpret the large amount of data collected, we ask for an extension of the DFG support by two years. New far-reaching implications for quasar physics - especially for the geometry and kinematics of the central region, as well as the interplay between accretion disk, broad-line region and dust-torus - are guaranteed and will be published during the extension of the project.
