Scalar particles like axion or Higgs boson may play essential roles for the long-standing problem of dark matter and baryogenesis in particle cosmology. Besides the traditional approaches to unravel these puzzles, we study new indirect search for dark matter and baryogenesis by radio signals and gravitational waves signals in synergy colliders signals at near future radio telescope experiments (SKA, FAST, GBT) and laser interferometer experiments(LISA, Taiji/Tianqin).
