Research Abstract

In order to open up a new observational/experimental window to the ultimate theory, we have studied axions from both the cosmophysics phenomenology aspect and the superstring/supergravity aspect and have published more than 200 papers. The main achievements are demonstarations of the axion bose nova phenemenon caused by a rotating black hole by numerical simulations and the discovery of its observability by gravitational wave experiments, derivation of a parameter range for axion to resolve the conflict between the high energy gamma-ray observations and the infrared background observation, evaluations of the influences of axions produced by the decay of heavy moduli on cosmic microwave background and derivation of constraints on the compactification of extra-dimensions on the basis of this estimation, derivation of constraints on elementary particle models from cosmological influences of axionic isocurvature perturbations and topological defects.
