我们提供了一个汇编的58个发光SDSS 2型活动星系核在0.3(25/42或>59%)的HST图像显示出清晰的特征的形态扰动,在大多数情况下,确定合并/相互作用过程。我们讨论这一点的背景下,2型类星体和强大的射电星系的相关工作。 本文利用VLT、HST和SDSS的成像和光谱数据,详细研究了射电宁静2型类星体SDSS J143027.66-005614.8在z=0.32时的特殊情况。我们讨论的背景下,星系合并/相互作用的理论和观测研究的对象和它们的作用,在最明亮的活动星系的核和星星形成活动的触发的全球属性。
We present a compilation of HST images of 58 luminous SDSS type 2 AGNs at 0.3 25/42 or >59%) show clear signatures of morphological disturbance which are in most cases identified with merger/interaction processes. We discuss this in the context of related works on type 2 quasars and powerful radio galaxies. We study in detail the particular case of the radio quiet type 2 quasar SDSS J143027.66-005614.8 at z=0.32 based on VLT, HST and SDSS imaging and spectroscopic data. We discuss the global properties of the object in the context of theoretical and observational studies of galaxy mergers/interactions and their role in the triggering of the nuclear and star formation activities in the most luminous active galaxies.
