Fast non-relativistic and even relativistic outflows occur frequently in cosmic high-energy radiation sources and have been identified as the main contributors to the apparent luminosity by their nonthermal radiation. One common central issue of these intense cosmic radiation sources is the understanding of the dissipation processes of the available free kinetic energy in the surrounding collision-free interstellar and intergalactic plasmas. Our project is concerned with the microphysical plasma processes of this dissipation mechanism. Confinement by self-generated electromagnetic turbulence is also important for galactic and interplanetary cosmic rays.

在宇宙高能辐射源中，非相对论性甚至相对论性的快速外流是经常发生的现象，它们的非热辐射对视光度的贡献是主要的。这些强烈的宇宙辐射源的一个共同的中心问题是在周围的无碰撞的星际和星系间等离子体的可用自由动能的耗散过程的理解。我们的项目是关注这种耗散机制的微观物理等离子体过程。自生电磁湍流的限制对银河系和行星际宇宙射线也很重要。
