We propose to conduct a comprehensive study of relatively nearby galaxies hosting Active Galactic Nuclei, by means of spatially resolved integral field spectroscopy. Our driving scientific aims are: (i) to explain the unusual stellar population properties of AGN host galaxies, in particular by discriminating between 'shutdown' and 'rejuvenation' scenarios; (ii) to classify AGN hosts into kinematically undisturbed vs. affected by mergers, and establish a solid statistical basis for the importance of merger events for low-luminosity AGN; (iii) to collect evidence for AGN-driven outflows, and estimate their energetic relevance for the evolution of these galaxies.For this endeavour we plan to take advantage of the international CALIFA project, a major legacy survey to observe 600 galaxies with integral field spectroscopy, just commencing at Calar Alto observatory. We were already centrally involved in initiating, planning, and implementing CALIFA as a multilateral collaboration, and we now seek for funding to actively participate in its production phase and lead the scientific exploitation for the topic of AGN host galaxies. The key advantage of CALIFA for this topic will be the availability of spatially resolved spectra for a significant sample of AGN together with data of identical quality for many normal, inactive galaxies. We also have secured other unique datasets of AGN hosts that already promise to provide new insights into the science questions listed above.

我们建议通过空间分辨积分场光谱的方法，对活动星系核所在的相对较近的星系进行全面的研究。我们的主要科学目标是：(I)解释活动星系核宿主星系不同寻常的恒星群性质，特别是通过区分“关闭”和“复兴”情景；(Ii)将活动星系核宿主分为运动学上未受干扰的活动星系核和受合并影响的活动星系核宿主，并为低亮度活动星系核合并事件的重要性建立坚实的统计学基础；(Iii)收集活动星系核外流的证据，并估计它们与这些星系演化的能量相关性。为此，我们计划利用国际CALIFA项目，这是一项用积分场光谱观测600个星系的重大遗产调查，刚刚在Calar Alto天文台开始。我们已经作为一个多边合作中心参与了Califa的发起、规划和实施，现在我们正在寻求资金，以积极参与其生产阶段，并领导对AGN宿主星系主题的科学开发。CALIFA在这个问题上的主要优势将是可以获得大量活动星系核样本的空间分辨光谱，以及许多正常的、不活跃的星系的相同质量的数据。我们还获得了AGN宿主的其他独特数据集，这些数据集已经承诺为上面列出的科学问题提供新的见解。
