编辑了一个样本,其中包括71个Gev伽玛射线噪的活动星系核(14个BL Lac天体和57个平谱射电类星体),53个FRⅠ型射电星系和63个FRⅡ型射电星系.文章采用了非线性最小二乘法来拟合这个样本.当假设 M v =-23.0时,得到一个达到最佳拟合的哈勃常数,其拟合值为 H 0 =71.5±3.8kms -1Mpc -1.该值与通过哈勃望远镜关键计划所得到的哈勃常数值H 0=71.5±8 kms -1Mpc -1 符合得很好.其结果表明活动星系核的Gev伽玛辐射可以被用作宇宙标准烛光.

In this work,we compile a sample which contains 71 Gev Gamma-ray-loud Active Galactic Nuclei (AGNs)(14 BL Lacs and 57 FSRQs),53 FR Ⅰ radio galaxies and 63 FR Ⅱ radio galaxies.We make a nonlinear least-square fit to this sample,and find that the best fit value of the Hubble constant is H 0 =71.5±3.8km s -1 Mpc -1 with a reduced χ 22.46 by assuming M v =-23.0 and accepting q 0 =1.0,and the corresponding regression line has a correlation index R 0.78.The best fit value of H 0 =71.5±3.8 km s -1 Mpc -1 is in well agreement with H 0 =72±8 km s -1 obtained by the Hubble Space Telescope Key Project.Our results show that the Gev Gamma-ray emissions of AGNs can be used as cosmological standard candles indeed.
