论文摘要
在本文中，研究了通过超高能宇宙射线（UHECR）与乳乳外背景辐射相互作用的超高能宇宙射线（UHECR）的产生。 Centaurus A被认为是UHECR的主要来源，并且通过研究UHECR传播中产生的次级中微子和光子来识别该来源的可能性。模拟了三个有关三个磁外磁场（EGMF）和五个组合物的天体物理模型。研究了中微子和光子的通量和到达方向。结果表明，在几年内，目前的观测值以及在不久的将来提出的实验可以实现具有统计显着性的CEN A信号的检测。还提出了结果对模型的依赖性。
In this paper, the production of neutrinos and photons by ultra high energy cosmic rays (UHECR) interacting with the extragalactic background radiation is studied. Centaurus A is assumed as the prime source of UHECR and the possibility to identify this source by detecting the secondary neutrinos and photons produced in the propagation of UHECR is investigated. Fifteen astrophysical models regarding three extragalactic magnetic fields (EGMF) and five composition abundances are simulated. The flux and arrival direction of neutrinos and photons are investigated. It is shown that the detection of a signal from Cen A with statistical significance is achievable by current observatories in a few years and by proposed experiments in the near future. The dependence of the results on the models is also presented.
