Self-generated electromagnetic fields: Instabilities and energetic charged particle beams

快速的非相对论性甚至相对论性外流在宇宙高能辐射源中经常发生，并且通过它们的非热辐射被确定为表观光度的主要贡献者。这些强宇宙辐射源的一个共同的中心问题是对周围无碰撞的星际和星系间等离子体中可用自由动能耗散过程的理解。我们的项目是关于这种耗散机制的微物理等离子体过程。自生电磁湍流对星系和行星际宇宙射线的约束也很重要。

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.
