标题： Study of blazars detected by Fermi-LAT as high-energy neutrino sources

摘要： 除了由冰立方探测器（IceCube）检测到的中微子源NGC 1068外，IceCube-170922A中微子与处于多个波段（从射电到高能伽马射线）耀变体处于耀发状态的关联性已被提出，但高能中微子的产生位置和机制仍存在争议。 诸如类星体、耀变体、射电星系以及伽马射线暴等河外源被提议作为高能中微子的前身天体。 在这项工作中，我们研究了费米-伽马射线太空望远镜（Fermi-LAT）在4LAC目录中报告的耀变体，这些耀变体位于冰立方报告的中微子最佳拟合位置误差圈的90%范围内。 我们提出了一个单区电子强子模型来描述宽带谱能量分布，并估算每个源方向的中微子数量进行比较。还简要讨论了结果。 显示英文摘要

摘要： Besides the neutrino source detected by IceCube, NGC 1068, the association of the IceCube-170922A neutrino with the blazar in a flaring state among several wavelengths (from radio up to high-energy (HE) gamma-rays), the site and mechanisms of production of HE neutrino remains in discussion. Extragalactic sources such as Quasars, Blazars, Radio galaxies, and Gamma-ray bursts have been proposed as progenitors of HE neutrinos. In this work, we study the Blazars reported by Fermi-LAT in the 4LAC catalog, which are embedded inside the 90\% error of the best-fit position from the neutrinos reported by IceCube. We propose a one-zone lepto-hadronic scenario to describe the broadband Spectral Energy Distribution and then estimate the number of neutrinos to compare with those in the direction of each source. A brief discussion is provided of the results.
