论文摘要
结果表明，与仙女座星系中超级质量黑洞的生长和过去活动相关的相对论喷射可能是宇宙射线的主要来源，能量超过$ 10^{15} $ eV。大多数宇宙射线能量与射流的弓形冲击有关，该射流产生带有光组成的多PEV宇宙射线。射流本身产生具有重成分的最高能量宇宙射线。计算并与观测值进行比较，并将其与观测值进行比较，并将其传播到地球。
It is shown that the relativistic jets associated with the growth and past activity of the supermassive black hole in the Andromeda galaxy could be the main source of cosmic rays with energies above $10^{15}$ eV. Most of the cosmic ray energy is related to a bow shock of the jet that produces multi-PeV cosmic rays with light composition. The highest energy cosmic rays with heavy composition are produced in the jet itself. The spectra of energetic particles produced in Andromeda galaxy and propagated to the Earth are calculated and compared with observations.
