论文摘要
经常提出，活性银河核（AGN）中的相对论喷射与宿主星系的形态存在明显的关系。特别是，相对论的喷气机通常与合并事件有关。在这里，我们首次提出了Seyfert Galaxy的详细光谱和形态分析，SDSS J211852.96-073227.5，$ z = 0.26 $。该来源先前已被归类为伽马射线发射窄线Seyfert 1 Galaxy。我们用650万粘土望远镜重新观察了它，这些新的高质量光谱数据表明，它实际上是一个中等型的Seyfert Galaxy。此外，建模使用650万Baade望远镜获得的$ ks $ band近红外图像的结果表明，AGN是由互动系统中的晚期星系托管的，从而加强了星系相互作用和相对性射击之间的建议。
It has been often suggested that a tangible relation exists between relativistic jets in active galactic nuclei (AGN) and the morphology of their host galaxies. In particular, relativistic jets may commonly be related to merging events. Here we present for the first time a detailed spectroscopic and morphological analysis of a Seyfert galaxy, SDSS J211852.96-073227.5, at $z = 0.26$. This source has previously been classified as a gamma-ray emitting narrow-line Seyfert 1 galaxy. We re-observed it with the 6.5m Clay Telescope and these new, high-quality spectroscopic data have revealed that it is actually an intermediate-type Seyfert galaxy. Furthermore, the results of modelling the $Ks$-band near-infrared images obtained with the 6.5m Baade Telescope indicate that the AGN is hosted by a late-type galaxy in an interacting system, strengthening the suggested connection between galaxy interactions and relativistic jets.
