• The long-term monitoring results of brightness variation obtained by the optical telescope of Yunnan Observatory

    The luminescent variant is a rare and special type of active galactic nucleus, which is currently the most likely candidate for high-energy neutrinos. Its relativistic jet may be the origin of ultra-high-energy cosmic rays and neutrinos. Light variation is the most basic feature of the luminescent variant. The complexity of light variation research lies in the internal mechanism and geometric structure of the jet, the change of accretion disk, supermassive double black holes, gravitational lens and other factors may lead to light variation, And the origin of light change may…
