论文摘要
TXS 0506+056是2017年9月22日观察到的极端能源中微子事件IceCube-170922a的来源。费米 - 拉特探测器报告了高能（HE）$γ$ -RARE FLARE在2017年9月15日开始从该来源开始。几项尝试追踪IceCube-170922a周围非常高的能量（VHE）伽马射线对应物的尝试并没有成功。直到9月28日之后，主要的大气伽马射线成像Cherenkov（魔术）望远镜才观察到100 GEV以上的Blazar的第一个VHE伽马射线。 $ \ sim $ 41小时的调查导致VHE- $γ$射线活动直到2017年10月31日。在这里我们提出了扩展的GEV $γ-$射线，可以通过使用两个生产渠道，分别使用Electron Synchrotron Self Compton和Proton Synchrotron来解释HE和VHE发射。可以用$ {l_p'} {\ simeq} 10^{47} $ erg/sec在2.4 g的磁场和磁场中用$ {l_p'} {\ simeq} 10^{47} $ erg/sec来解释Vhe的45天VHE排放。
TXS 0506+056, a source of the extreme energy neutrino event, IceCube-170922A, was observed on 22 September 2017. The Fermi-LAT detector reported high energy (HE) $γ$-ray flare between 100 MeV and 100 GeV starting from 15 September 2017 from this source. Several attempts to trace the very high energy (VHE) gamma-ray counterparts around the IceCube-170922A resulted in no success. Only after 28 September, the Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes observed the first VHE gamma-rays from the blazar above 100 GeV. The $\sim$ 41 hr survey resulted in VHE-$γ$ ray activity till 31 October 2017. Here we propose the extended GeV $γ-$rays can be explained by taking two production channels, electron synchrotron self Compton and proton synchrotron for HE and VHE emissions, respectively. The 45 days of VHE emission from the peak of the HE-flare can be explained with $ {L_p'}{\simeq}10^{47}$ erg/sec in the jet frame and magnetic field of 2.4 G, consistent with the ${L}_{Edd}$ for a blackhole mass $5\times 10^{9} {M}_\odot$
