论文摘要
在本文中,旋转电磁级联反应用作宇宙射线源的探针。这是如下的。在乳清外太空中,宇宙射线启动了电磁级联,其中伽马射线和中微子发射出现。我们使用宇宙射线数据的联合分析以及乳清外伽马射线和中微子的发射,研究超级黑洞附近的颗粒加速度。颗粒注射光谱取决于粒子加速的过程,在这里我们讨论了各种注入光谱的模型。使用公共可用的传输代码进行了宇宙射线传播的计算。已经发现,可能存在一个新的子类,它不影响地球上的粒子通量,而是在电磁级联反应中引起的伽马射线和中微子排放。此外,得出了被超弹力磁场包围的“外来”超质量黑洞的相对数量的上限。
In this paper intergalatic electromagnetic cascades are used as a probe of cosmic ray sources. This is achieved as follows. In extragalactic space cosmic rays initiate electromagnetic cascades in which gamma-ray and neutrino emission arises. We used the joint analysis of cosmic ray data, along with extragalactic gamma-ray and neutrino emission, to study particle acceleration in the vicinity of supermassive black holes. Particle injection spectra depend on processes of particle acceleration, and here we discuss models with various injection spectra. The computation of the propagation of cosmic rays in space were performed using the publicly avaliable TransportCR code. It was found that a new subclass of sources might exist that does not contribute to the particle flux on Earth, instead to gamma-ray and neutrino emissions arising in electromagnetic cascades. In addition, the upper limit of the relative number of 'exotic' supermassive black holes surrounded by a superstrong magnetic field is derived.
