本文介绍了3CR和B2星表中140个射电星系的远红外观测结果。这些星系的射电功率范围超过四个数量级，从附近星系的弱核源到中等红移的强大FR II双叶源。IRAS的扫描或定点观测在至少一个波段上探测到38个射电星系; 21个在60和100 μm波段上都探测到。远红外辐射的强度与核心射电辐射的关系比与总射电辐射的关系更密切，并且与宿主星系的绝对视星等无关。较明亮的3CR星系比较不明亮的B2星系有较温暖的远红外辐射
Far-infrared observations of 140 radio galaxies from the 3CR and B2 catalogs are presented. The galaxies span a range of over four orders of magnitude in radio power, from weak nuclear sources in nearby galaxies, to powerful FR II doubled-lobed sources at moderate redshift. Scanned or pointed observations with IRAS detect 38 of the radio galaxies in at least one waveband; 21 are detected at both 60 and 100 μm. The strength of the far-infrared emission is more closely correlated with core radio emission than with total radio emission, and it is independent of the absolute visual magnitude of the host galaxy. The more luminous 3CR galaxies have warmer far infrared emission than the less luminous B2 galaxies
