Current Research

There are thermal plasmas, magnetic fields, and non-thermal high-energy particles (cosmic ray) in several scales of the universe, such as, planets, stars, galaxies, galaxy clusters. We are studying how the magnetic field and cosmic rays has been generated in the several scales from the beginning of the universe to now.
