论文摘要
Blazars是最活跃的伽马射线射线源。它们显示出零星的活动爆发，持续数小时到几个月。在这项工作中，我们介绍了Fermi-Lat（100 MeV-300 GEV）检测到的光源样本的10年分析。使用2周的binned Lightcurves（LC），我们估计了占空比（DC）：源源处于活性状态的时间的一部分。这些对象呈现不同的DC值，在考虑（而不是）省级背景光（EBL）时，平均$ 22.74 \％$ $ \％\％\％\％$。此外，我们研究了十年的数据中选定的Blazars样品样本的所谓“ Blazar序列”趋势。该分析限制了在静止状态期间子-PEV中微子发射的可能对应物，从而使解释在耀斑状态期间观察到的Icecube信号的可能性。
Blazars are the most active extragalactic gamma-ray sources. They show sporadic bursts of activity, lasting from hours to months. In this work we present a 10-year analysis of a sample of bright sources detected by Fermi-LAT (100 MeV - 300 GeV). Using 2-week binned lightcurves (LC) we estimated the Duty Cycle (DC): fraction of time that the source spends in an active state. The objects present different DC values, with an average of $22.74\%$ and $23.08 \%$ when considering (and not) the Extragalactic Background Light ( EBL). Additionally we study the so called "blazar sequence" trend for the sample of selected blazars in the ten years of data. This analysis constrains a possible counterpart of sub-PeV neutrino emission during the quiescent states, leaving the possibility to explain the observed IceCube signal during the flaring states.
