Particle transport, composition, and acceleration at shocks in the heliosphere.The physics of energetic charged-particle transport in the inner heliosphere is discussed in the context of spacecraft observations, and their connection to anomalous cosmic rays and the outer heliosphere. It will be argued...
Particle acceleration and formation of jets in the cores of active galactic nuclei We propose a new mechanism of formation of jets in the cores of AGN. A beam of very-high energy particles is produced in the vicinity of the black hole hor... A Neronov,D Semikoz - 《New Astronomy Review...
Besides solar flares and CMEs, which are transient events, acceleration of particles has also been observed in other places in the solar system, including the solar wind termination shock, planetary bow shocks, and shocks bounding the Corotation Interaction Regions (CIRs). Understanding how ...
aIf the forces acting on a particle are not balanced, the particle will experience an acceleration proportional to the resultant force and in the direction of the resultant force. 如果行动在微粒的力量不是平衡的,微粒将体验加速度比例与合力和朝合力的方向。 [translate] ...
However, because observations of energetic particles are often made at spacecraft near the Earth,propagation of energetic particles in the solar wind smears out many distinct features of the acceleration process. The propagation of a c...

[1] Particle acceleration in space plasmas, particularly at collisionless shocks, remains a fundamental yet poorly understood problem in space physics. The most important questions that need to be addressed include (1) where are the particles accelerated, (2) what source material is available for ...
