从射电结构的角度评述了BLLac天体和FR-I射电星系的统一模型的最新进展,内容包括射电结构,延展射电光度(Pext),最大角尺度(LAS),射电核主导系数(f)的比较以及对相对论聚束的测试。最新的射电观测资料表明XBLs是介于FR-I和RBLs之间的过渡型天体,这对BLLac天体是聚束的FR-I射电星系提供了一个很好的证据。  相似文献

5个新发现的X选BL Lac天体   总被引:1,自引:0,他引:1  
利用ROSATVLA方法筛选,从ROSATX射线源中选出了一批新的BLLac天体和类星体的候选体.1996年12月8日至17日,利用北京天文台2.16m望远镜和新从美国引进的OMR摄谱仪,对这批新候选体进行了光谱认证.经SUN工作站处理,又发现了5个新的X选BLLac天体.此外,还对去年作者在OMR引进之前发现的BLLac天体进行了检验,结果发现,去年发现的7个BLLac天体中,2322+343的CaIIH&K“Breakstrength”为26.9%,稍大于判据25%,因此,2322+343到底是BLLac天体还是射电星系还有待于进一步测光及偏振观测的验证.  相似文献
