The interstellar medium (ISM)
occupies much of modern astrophysicists'
research efforts. This complicated
environment -- filled with various
gas components, magnetic fields, cosmic-ray
particles, turbulence and gravitational
fields originated from the galactic
stars and ISM itself -- gives rise
to a variety of magnetohydrodynamics
phenomena. In particular, our studies
have been focused on problems related
to the formation of giant molecular
clouds and HI super-cloud and the
dynamics of the galactic ISM gaseous
disk.
-- There
are so many astrophysical sources
of gravitational wave in the Universe.
In order to fully understand the phenomena
we need comprehensive simulations
of collisions between compact objects
such as black holes and neutron stars,
and collapse of a star to a black
hole. Basically, we are devoted to
solving the Einstein equation with
huge amounts of computing resources
including Grid computing environment.
In particular, a group
of numerical relativity was established in 2005 for the first time in Korea.
This is a
collaborative organization of people who are working in various fields such as
physics, astrophysics, and computational sciences. The members of this group are
actively working on the topics described above. The details can be seen in the
home page of the Korea Center for Numerical Relativity (KCNR);
http://www.ksc.re.kr/kcnr/
.
-- The
theoretical and numerical astrophysics
research group utilizes KISTI supercomputing
resources to understand the physics
associated with the galactic large-scale
structures and gravitational wave
phenomena. The group is interested
in the development and application
of numerical methods for astrophysical
fluid dynamics and relativistic fluid
dynamics. In addition, we devoted
ourselves to constructing a virtual
environment for numerical astrophysics
research under the basis of CACTUS
Grid technology.
