巡天和BL Lac天体的Radio-X-ray谱指数

Surveys and radio-X-ray spectral index of BL Lacs

摘要: 经典和近些年的深度Blazar巡天都表明Radio-X-ray谱指数rαx与同步辐射峰频νpeak有很好的反相关性,但后者却显示出对给定的νpeak,rαx的散射很大,不能由νpeak来导出αrx,这个差异可能源自巡天策略.

Abstract: Both the classic-and the resent-deeper-blazar surveys have presented an anti-correlation for αrx versus νpeak,but the latter exhibits such a broad scatter trend in νpeak for any given value of αrx that it is impossible to derive αrx from νpeak.The reason behind this may originate from their individual searching strategies.
