摘要

射电星系的强烈活动应该导致几乎无处不在的化石射电等离子体存在于星系间介质的密度较大的区域,如星系团、星系群和星系细丝。这种化石无线电等离子体通过磁约束可以包含大量的相对论性粒子(电子和可能的质子)。这些颗粒可能在湍流和冲击波等环境影响下被释放和/或重新激活。讨论了这些过程与观测到的星系团(星系团射电晕和星系团射电遗迹)中漫射射电发射源形成的可能联系。

Particle Acceleration and Diffusion in Fossil Radio Plasma
The strong activity of radio galaxies should have led to a nearly ubiquitous presence of fossil radio plasma in the denser regions of the inter-galactic medium as clusters, groups and filaments of galaxies. This fossil radio plasma can contain large quantities of relativistic particles (electrons and possibly protons) by magnetic confinement. These particles might be released and/or re-energized under environmental influences as turbulence and shock waves. Possible connections of such processes to the formation of the observed sources of diffuse radio emission in clusters of galaxies (the cluster radio halos and the cluster radio relics) are discussed.
