来自遥远耀变体产生的宇宙射线的次级光子和中微子

Secondary photons and neutrinos from cosmic rays produced by distant blazars

摘要:

遥远活动星系核(AGN)发射的宇宙线质子与视线方向的光子背景相互作用产生的次级光子和中微子,可以揭示关于星系际磁场(IGMF)、河外背景光(EBL)和宇宙射线加速机制的大量新信息。次级光子可能已经被伽马射线望远镜观测到了。我们表明,二次中微子提高发现遥远的耀变体的冰立方的前景,我们讨论的宇宙背景,磁场,和AGN模型的分歧。

英文摘要:

Secondary photons and neutrinos produced in the interactions of cosmic ray protons emitted by distant Active Galactic Nuclei (AGN) with the photon background along the line of sight can reveal a wealth of new information about the intergalactic magnetic fields (IGMF), extragalactic background light (EBL), and the acceleration mechanisms of cosmic rays. The secondary photons may have already been observed by gamma-ray telescopes. We show that the secondary neutrinos improve the prospects of discovering distant blazars by IceCube, and we discuss the ramifications for the cosmic backgrounds, magnetic fields, and AGN models.
