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

在宇宙高能辐射源中经常出现快速、非相对论甚至相对论的流出现象，它们的非热辐射被认为是造成表观光度的主要因素。这些强宇宙辐射源的一个共同中心问题是理解周围无碰撞的星际和星际等离子体中可用自由动能的耗散过程。我们的项目是关于这种耗散机制的微物理等离子体过程。自身产生的电磁湍流的限制对银河系和行星际宇宙射线也很重要。

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.
