摘要

最近的观测揭示了活动星系核在高能中微子的产生中所起的重要作用。在这项研究中,我们重点研究了一个天体,5BZB J0630−2406,它是最近提出的在冰立方观测的前7年中与中微子发射有关的blazars之一。模拟准同步、宽带光谱能量分布,我们探索了从纯轻子模型到细子模型的各种场景,测试了外部光子场的包含。这一理论研究为提出的中微子-耀变体关联提供了一个补充的试验场。尽管历史上被归类为BL Lac,但我们的研究表明,5BZB J0630−2406属于相对罕见的高功率平谱射电类星体亚类。我们的结果表明,质子和外部辐射场之间的相互作用可以产生在冰立方探测器范围内的中微子通量。此外,x射线发射的光谱形状表明与高能质子有关的强子过程的印记。

Hadronic Processes at Work in 5BZB J0630−2406
Abstract Recent observations are shedding light on the important role that active galactic nuclei play in the production of high-energy neutrinos. In this study, we focus on one object, 5BZB J0630−2406, which is among the blazars recently proposed as associated with neutrino emission during the first 7 yr of IceCube observations. Modeling the quasi-simultaneous, broadband spectral energy distribution, we explore various scenarios from purely leptonic to leptohadronic models, testing the inclusion of external photon fields. This theoretical study provides a complementary testing ground for the proposed neutrino–blazar association. Despite being historically classified as a BL Lac, our study shows that 5BZB J0630−2406 belongs to the relatively rare subclass of high-power flat-spectrum radio quasars. Our results indicate that interactions between protons and external radiation fields can produce a neutrino flux that is within the reach of the IceCube detector. Furthermore, the spectral shape of the X-ray emission suggests the imprint of hadronic processes related to very energetic protons.
