Survey of cosmic magnetic fields
Cosmic magnetic fields are pervasive in interstellar and intercluster space,
and magnetism is one of the four fundamental forces. They are known to play
important roles in the processes of star formation, turbulence, cosmic-ray
acceleration and galaxy formation. However, the origin and structure of the
cosmic magnetic fields and their roles in the above mentioned processes are
poorly known. In this talk, I will review the understanding of the cosmic
magnetic field. Focus will be given to the Galactic magnetic field revealed
by the Faraday rotation of the linearly polarized radiation. Then I will
briefly mention a survey science of cosmic magnetism, one of the key
sciences
of the SKA (Square Kilometre Array), that will certainly provide
new insights on cosmic magnetic fields.
