论文摘要

有史以来第一次识别宇宙射线加速器是Icecube事件170922a的空间和时间相关的结果,并张开了Blazar TXS 0506+056,激发了我们在Fermi-Lat 3FGL 3FGL Catalog中寻找其他flermi-lat Catalog中的其他燃烧的Blazar,这可能会与ICECEBE ENTICE EFERS相关。我们已经研究了与中微子轨道事件相关的Blazars的Fermi-LAT光曲线。在我们研究中选择的IceCube轨道事件的2 $σ$角度不确定性中确定的八个来源中,我们发现在中微子检测期间,只有一个源3FGL J2255+2409处于凸起状态。我们已经对此Blazar的多波长数据进行了时间依赖性建模,以及中微子事件,包括其射流中的Leptonic Energe损失和Proton-Proton相互作用,以确定它是否可以是中微子事件的起源。我们的Lepto-Hadronic模型估计了$ L_J = 3.6 \ times10^{47} $ erg/sec的射流光度,在3FGL/4FGL J2255+2409的中微阶段。

The first ever identification of a cosmic ray accelerator as the consequence of spacial and temporal correlation of IceCube event 170922A with flaring of a blazar TXS 0506+056 motivated us to look for other flaring blazars in Fermi-LAT 3FGL catalog, which could be correlated with IceCube high energy track events. We have studied the Fermi-LAT light curves of blazars correlated with neutrino track events. Among the eight sources identified within 2$σ$ angular uncertainty of the IceCube track events selected in our study, we find only one source 3FGL J2255+2409 was in flaring state during the neutrino detection. We have carried out a time dependent modelling of the multi-wavelength data from this blazar, and the neutrino event including leptonic energy losses and proton-proton interactions in its jet to determine whether it could be the origin of the neutrino event. Our lepto-hadronic model estimates a jet luminosity of $L_j = 3.6 \times10^{47}$ erg/sec during the neutrino phase of 3FGL/4FGL J2255+2409.
