| 英文摘要 | Magnetic monopoles have been a trending topic among physicists and astronomers since the 1930s. Researchers have been working hard to find evidence of magnetic monopoles in laboratories. The existence of magnetic monopoles can rationally explain the stability of charges, the quantization of charges, the structure of leptons, the unified composition of leptons and hadrons, and the symmetry of leptons and quarks. The presence of these mysterious particles in the universe could have significant implications for theoretical physics and astrophysics. The Grand Unified Theory has also predicted the existence of magnetic monopoles, which is interestingly implied by some astronomical observations. Noticing that the growth of supermassive black holes in the early universe is an increasingly challenging difficulty faced by astronomers, here we argue that it could be solved with the help of magnetic monopoles. As suggested by Peng et al. in A Monopole Model for Galactic Nuclei. In: Structure and Evolution of Active Galactic Nuclei, vol. 121, p. 663 (1986), quasars containing magnetic monopoles at the center can continuously catalyze the decay of protons to release energy. We examine this model by using quasar data from the Sloan digital sky survey. It is shown that the initial mass distribution of quasars derived from the magnetic monopole model exhibits a Gaussian distribution. At the same time, the initial mass function is also slightly higher than previously expected, which could be verified by future observations. |
