Blazar天体光变时标的结构函数研究

The SF research for time-scale of Blazars variability

  • 摘要: 采用结构函数分析提供的定量分析时变特征方法,利用云南天文台获得的观测数据,对活动星系核的一个子类——Blazar天体的短时标光变曲线进行了分析研究.结果表明,射电选的BL Lac天体有较高的短时标光变观测率,而Blazar中各子类(RBL,XBL和QSO)的结构函数特征无明显差异存在.

     

    Abstract: By means of the method of structure function(SF) analysis for quantifying temporal characteristic of the variability,using the observational data from Yunnan Observatory,it have been studied that the intranight light curve of blazar,a subclass of active galactic nuclei.Among these observations of blazars,more intranight variabilities have been detected in radio-selected BL Lac objects(RBL).There is no obvious difference of SF between the RBLs, XBLs and QSOs.
