摘要:

在本文中,我们提出的MAGNA(多重活动星系核活动)计划的全面研究,旨在多超质量黑洞系统的概述。主要目标是在不同的演变阶段合并系统的源的特性,我们选择了一个样本的对象光学分类为多个系统的基础上的发射线诊断,并开始了大规模的多波段观测活动。本文报道了异常高密度致密活动星系核群SDSS~ J 0959 +1259的发现。多波段研究表明,星系之间通过潮汐力发生强相互作用,因此该系统是触发核活动和恒星形成的物理机制的案例研究。本文还对多重活动星系核系统SDSS~J1038+3921作了初步分析。

英文摘要:

In this paper we present an overview of the MAGNA (Multiple AGN Activity) project aiming at a comprehensive study of multiple supemassive black hole systems. With the main goal to characterize the sources in merging systems at different stages of evolution, we selected a sample of objects optically classified as multiple systems on the basis of emission line diagnostics and started a massive multiband observational campaign. Here we report on the discovery of the exceptionally high AGN density compact group SDSS~J0959+1259. A multiband study suggests that strong interactions are taking place among its galaxies through tidal forces, therefore this system represents a case study for physical mechanisms that trigger nuclear activity and star formation. We also present a preliminary analysis of the multiple AGN system SDSS~J1038+3921.}
