Title: 8th Korean Astrophysics Workshop on
Astrophysics of High-Beta Plasma in the Universe
When: 10 -- 13 November, 2014
Where: ShineVille Resort, Jeju Island, Korea
Homepage: http://sirius.unist.ac.kr/kaw8/
------------------------------------------------------------------------
Scientific Rationale
- Most of the baryonic matter in the universe is in the form of hot,
collisionless, high-beta plasma. Two such important environments,
their similarities and differences provide the motivation for this
workshop; the intracluster media of galaxy clusters (ICMs) and the
interplanetary medium (IPM). The first is vast, but remote; the
second is the only high beta plasma directly accessible to in situ
measurements.
- ICMs have been recognized over the past two decades as not only the
dominant baryonic component of galaxy clusters, but also vital
elements in their formation and evolution, the formation and
evolution of the individual galaxies, as well as essential cluster
diagnostic tools. The ICMs are highly dynamic, penetrated by shocks
and other discontinuities and apparently turbulent.
- ICMs may also provide a unique, if remote, laboratory for basic
plasma physics. Yet, important microphysical processes in the ICM,
such as those controlling dissipation, conduction, turbulence,
magnetic field evolution and energetic particle acceleration, are
poorly understood.
- The IPM is also a collisionless, moderately high beta plasma
containing shocks, other discontinuities and turbulence. In these
characteristics it is similar to the ICM and distinct from typical
terrestrial laboratory plasmas. Because of its proximity to Earth
and accessibility to in situ measurements, microphysical processes
and dynamical states of the IPM are much better understood than
those of the ICM. It may provide lessons relevant to the ICM.
- The plan for this workshop is to set up focused sessions through
which we hope to understand key plasma physical properties of the
ICM, as well as their roles, and to identify similarities and
contrasts with other plasma environments, especially the IPM, and to
extract valuable insights of common value to the broader community.
Topics to be covered
- Shock waves in the ICM and IPM
- Turbulence and magnetic fields in the ICM and IPM
- Magnetic reconnection in the IPM and ICM
- Particle acceleration, particle transport and diffusion in diffuse,
magnetized media
- Radio, X-ray, and gamma-ray observations of the ICM and their
interpretation
