标题： OMEGA: OSIRIS Mapping of Emission-Line Galaxies in A901/2

摘要： 这项工作介绍了使用10米GTC望远镜（拉帕尔马）上的OSIRIS仪器进行的ESO大型计划的首批结果。 我们观测了阿贝尔901/902系统区域（z ~ 0.165）中的大量星系，该区域作为STAGES项目的一部分已被广泛研究。 我们为覆盖广泛环境的大量星系获得了光谱和空间分辨的H-alpha和[NII]发射图。 新数据与广泛的多波长观测数据相结合，包括HST、COMBO-17、斯必泽、Galex和XMM成像，以研究恒星形成和AGN活动作为环境和星系特性（如光度、质量和形态）的函数。 最终目标是详细理解环境对恒星形成和AGN活动的影响。 显示英文摘要

摘要： This work presents the first results from an ESO Large Programme carried out using the OSIRIS instrument on the 10m GTC telescope (La Palma). We have observed a large sample of galaxies in the region of the Abell 901/902 system (z ~ 0.165) which has been extensively studied as part of the STAGES project. We have obtained spectrally and spatially resolved H-alpha and [NII] emission maps for a very large sample of galaxies covering a broad range of environments. The new data are combined with extensive multi-wavelength observations which include HST, COMBO-17, Spitzer, Galex and XMM imaging to study star formation and AGN activity as a function of environment and galaxy properties such as luminosity, mass and morphology. The ultimate goal is to understand, in detail, the effect of the environment on star formation and AGN activity.
