The ability to make simultaneous, multi-point measurements of field and plasma properties has substantially increased our knowledge of the structure and physics of collisionless shocks in space. In addition to allowing the determination of the large-scale macroscopic structure of such shocks as well ...
In addition, we find that the velocity distribution of downstream hydrogen atoms has three components. The observed shock structures suggest that diffusive shock acceleration can operate at perpendicular shocks propagating into partially ionized plasmas in real three-dimensional systems....
Charged particles can be accelerated to high energies by collisionless shock waves in astrophysical environments, such as supernova remnants. By interacting with the magnetized ambient medium, these shocks can transfer energy to particles. Despite increasing efforts in the characterization of these shocks...
Interestingly, this instability may explain electromagnetic turbulence also observed in collisionless shocks, which are common in energetic astrophysical phenomena.doi:10.1007/s10509-005-3936-yHantao JiCenter for Magnetic Self-Organization in Laboratory and Astrophysical Plasmas Princeton Plasma Physics ...

The occurrence of jets should not be restricted to the terrestrial magnetosheath. Instead, the phenomenon should be universal downstream of collisionless shocks. In Sect.8, jets downstream of other planetary and astrophysical shocks are discussed. We conclude this review paper with an outlook Sect.9...

Collisionlessshocks are the important physical phenomena in the space and cosmical plasmas. 无碰撞激波是空间等离子体和宇宙等离子体中的重要物理现象。 2. The results show that whistler waves can be directly excited by thecollisionlesscurrent sheet. ...
Magnetic reconnection is a leading mechanism for magnetic energy conversion and high-energy non-thermal particle production in a variety of high-energy astrophysical objects, including ones with relativistic ion-electron plasmas (e.g., microquasars or AG
Collective processes in plasmas often induce microinstabilities that play an important role in many space or laboratory plasma environments. Particularly notable is the Weibel-type current filamentation instability, which is believed to drive the creation of collisionless shocks in weakly magnetized astrophys...
