摘要
本文综述了连同红外天文卫星(1RAS)观测在内的对河外星系的红外观测研究的现状,其中包括椭圆星系,透镜星系,旋涡及棒旋星系等正常星系,也包括类星体,塞弗特星系及蝎虎BL天体等特殊星系以及星暴星系。本文还讨论了各种星系红外发射可能存在的辐射机制,并对某些红外观测结果提出了看法。
The present observational research including IRAS on extragalaxies in the infrared is reviewed in this paper. It refers not only to some normal galaxies, such as the Elliptical, the Lenticular, the Spiral and the Barred Spiral, but also to some peculiar galaxies, such as Quasar, the Seyfert and the BL Lac object as well as to the starburst galaxy. Possible radiation mechanisms in the infrared for such objects are discussed. Comments on some observational results are also presented.
