射电源射电源radiosource宇宙空间辐射无线电波的分立天体。大多数天体都可能是射电源,已发现的射电源有3万多个。射电源类型很多,按视角径大小可分为致密源和展源两类。致密源角径小于1″,大小仅为1~100光年,最小总能量在1045~1051焦耳间,常在类星体、特殊星系核内发现。展源角径大于1″,大小为3~200万光年,最小总能量在1051~1054焦耳间,常与亮椭圆星系相证认,40%的展源是双射电源。按距离也可把射电源分为银河系射电源和河外射电源两类。银河系射电源包括:21厘米中性氢区、电离氢区、超新星遗迹、射电星及脉冲星等。在河外射电源中,正常射电星系平均辐射功率在1030~1033焦耳/秒,只有光波段辐射的百万分之一;而特殊射电星系射电辐射功率比正常射电星系强102~106倍,接近或大于光波段的辐射功率,有时直接将特殊射电星系简称为射电星系;还有一种类星射电源是一种光学外貌似恒星,光谱线有很大红移的强射电源,如果认为它的红移是宇宙学红移,那么它也应该是河外射电源中的一种。
