Astrophysics Lab of Prof. Ryu The
universe contains cosmic plasma of baryonic matter, in addition to dark
matter and dark energy. The so-called nonthermal components
of the plasma, that is, shock waves, magnetic fields, cosmic rays and
turbulence, are expected to play significant roles in the formation and
observation of the large-scale structure of the universe. Yet their nature
and origin are not fully understood. In the lab, the cosmic plasma as well as
dark matter and dark energy are explored. Along with numerical simulations
for the formation of the cosmic web, theoretical arguments based on plasma
physical models for collisionless shock wave formation, cosmic ray
acceleration, astrophysical turbulence, and magnetic field generation are
employed. Research Areas ∙
Shock waves and turbulence in clusters of galaxies ∙
Origin and evolution of magnetic fields and cosmic
rays in the universe ∙
Plasma astrophysical phenomena in the large-scale
structure of the universe Education ∙
