使用MOJAVE目录和10年IceCube数据测试AGN射电和中微子相关性

Testing the AGN Radio and Neutrino correlation using the MOJAVE catalog and 10 years of IceCube Data

Abhishek Desai, Justin Vandenbroucke, Alex Pizzuto

摘要:

2017年9月22日,冰立方报告了一个高能中微子事件,该事件被发现与一个耀变体TXS 0506+056重合。这种多信使观测暗示耀变体对观测到的高能天体物理中微子有贡献,并提出了广泛的相关研究的必要性。最近的工作表明,伽马射线的内部吸收,以及它们与源和河外背景的内在相互作用,将导致缺乏高能伽马射线和中微子的相关性,同时暗示中微子与X射线和无线电波段的低光子能量观测之间的相关性。基于已发表的冰立方警报和射电观测的研究报告了伽马射线亮和伽马射线暗的活动星系核(AGN)中可能存在的射电中微子相关性。然而,由于可用数据有限,它们具有边际统计意义。我们提出了15 GHz的无线电观测活动星系核的MOJAVE XV目录和10年的IceCube探测器数据之间的相关性分析,并讨论了来自时间平均叠加分析的结果。

英文摘要:

On 22 September 2017, IceCube reported a high-energy neutrino event which was found to be coincident with a flaring blazar, TXS 0506+056. This multi-messenger observation hinted at blazars contributing to the observed high-energy astrophysical neutrinos and raised a need for extensive correlation studies. Recent work shows that the internal absorption of gamma rays, and their interactions intrinsic to the source and with the extragalactic background, will cause a lack of energetic gamma-ray and neutrino correlation while hinting towards a correlation between neutrinos and lower photon energy observations in the X-ray and radio bands. Studies based on published IceCube alerts and radio observations report a possible radio-neutrino correlation in both gamma-ray bright and gamma-ray dim active galactic nuclei (AGN). However, they have marginal statistical significance due to limited available data. We present a correlation analysis between 15 GHz radio observations of AGN reported in the MOJAVE XV catalog and 10 years of IceCube detector data and discuss the results derived from a time-averaged stacking analysis.
