摘要:

本文介绍了FRII射电星系PKS 2250 -41和PKS 1932 -46的光谱和成像观测结果。这两个源显示非常广泛的发射线区域,似乎正在经历与同伴机构的相互作用。除了与射电源的相互作用相关联的扰动气体运动学,更远的发射材料显示简单,狭窄的发射线配置文件,往往在显着的速度偏移从系统静止帧,并可能与潮汐碎片。

英文摘要:

We present the results of spectroscopic and imaging observations of the FRII radio galaxies PKS2250-41 and PKS1932-46. Both sources display very extensive emission line regions, and appear to be undergoing interactions with companion bodies. In addition to disturbed gas kinematics associated with interactions with the radio source, the more distant emitting material displays simple, narrow emission line profiles, often at significant velocity offsets from the system rest-frame, and may be associated with tidal debris.
