Abstract ritorna |
By flying instruments such as optical, X-ray and gamma-ray
telescopes in space and carrying out in situ measurements besides collecting
photons, up to the innermost regions of the Heliosphere we have gained new
perspectives on the Universe in terms of its complexity and of the variety
of phenomena that remain to be explained. The observations complemented by
advanced laboratory experiments have highlighted the limitations which, by
restricting a large fraction of our investigations to a reductionistic
approach, would entail. In fact, this approach would assign a secondary role
to the emergence of collective modes, to the explanation and description of
complexities, to the understanding and theory of self-organization
processes etc. In parallel with the evolution of observations on large scales
an increasing number of physical entities has been recognized as being plasmas
or as worth of being described as plasmas where, for instance, electromagnetic
or gravitational interactions or both prevail. Among the first ones the
so-called Galaxy Clusters are the largest plasma entities in the Universe and
have been identified as such by X-ray astronomy. Galactic disks are the most
studied gravitational plasmas and the plasmas that are envisioned to surround
"shining" black holes can be assigned to the third category as the
gravitational in electromagnetic interactions are equally relevant. To these,
have to be added dusty plasmas, cosmological plasmas, etc. In important cases
of astrophysical plasmas or of the high energy plasmas investigated for
nuclear fusion research, where the particle distributions in phase space have
significant departures from the thermal equilibrium state, relevant theories
have to deal frequently with processes involving 7 dimensions that is the
entire phase space in physical regimes where processes that require
consideration of quantum-mechanics can be ignored. A description of the
theories that have been developed or that are to be pursued is given. Major
open theoretical issues concerning astrophysical as well as thermonuclear
plasmas are identified. (Sponsored in part by the U.S. Department of Energy). |
