摘要:

2017年9月22日,冰立方中微子探测器探测到一个高能μ子中微子,与BL Lac天体TXS 0506+056的多波长耀斑相吻合,很可能证实活动星系核是高能宇宙射线和中微子的来源。本文用光强子模型解释了中微子事件发生后几天MAGIC望远镜观测到的极高能$γ$射线,并将模型推广到计算TXS 0506+056耀斑爆发期不同窗口的中微子通量,并与IceCube和MAGIC的估算结果进行了比较。我们也用这个模型来估计FSRQ PKS B1424-418耀斑的中微子通量,这被认为是与冰立方观测到的2 PeV中微子事件有关。

英文摘要:

The detection of a high energy muon neutrino on 22 September 2017 by IceCube neutrino detector coincides with the multiwavelength flaring from the BL Lac object TXS 0506+056, most likely confirming AGN as a source of high energy cosmic rays and neutrinos. Using the photohadronic model, we have explained the very high energy $γ$-rays observed by MAGIC telescopes few days after the neutrino event and extend the model to calculate the neutrino flux at different windows consistent with the flaring period of TXS 0506+056 and compared with the IceCube and MAGIC estimates. We also use this model to estimate the neutrino flux from the flaring of FSRQ PKS B1424-418 which is believed to be associated with the 2 PeV neutrino event observed by IceCube.
