GeV伽玛射线噪blazar天体观测特性的统计分析

Analysis of Observational Properties of GeV γ-ray Loud Blazars

收集了35个GeV伽玛射线噪blazar天体的从光学到伽玛射线波段观测数据.计算了αxγ,xαox,αγxγ,分析了Γγ和logpνeak,Γx和logνpeak以及Γx和Γγ的相关性,得出FSRQs具有较大的Γγ光子谱指数,对应的谱较陡,而HBLs具有较小的Γx光子谱指数,其谱较平.BL-Lacs和FSRQs的αxγ与xαox,αxox与αγxγ存在明显的负相关.

In this thesis, a sample of 35 GeV 7 - ray loud blazars, including the observation data from optical to y - ray energy band, was collected. The αxγ, αxx and aγxγ were calculated. The correlation analysis results are： For GeV 7 - ray blazars, the correlations of Гγ vs. logvpeak, Гx vs. logvpeak and Гx vs. Гx were investigated. It is found that ItBLs have small Гx spectral indices and PSRQs have larger Гx spectral indices. The correlations of αxγ vs. αγxγ and am vs. ant are strongly negative.
