Energy Partition of Thermal and Nonthermal Particles in Magnetic Reconnection

Masahiro Hoshino

Magnetic reconnection has long been known to be the most important mechanism as quick conversion of magnetic field energy into plasma kinetic energy. In addition, energy dissipatio…

Nonthermal Electron Acceleration at Collisionless Quasi-perpendicular Shocks

T. Amano, Y. Matsumoto, A. Bohdan +6

Shock waves propagating in collisionless heliospheric and astrophysical plasmas have been studied extensively over the decades. One prime motivation is to understand the nonthermal…

Theory of Electron Injection at Oblique Shock of Finite Thickness

Takanobu Amano, Masahiro Hoshino

A theory of electron injection into diffusive shock acceleration (DSA) for the generation of cosmic-ray electrons at collisionless shocks is presented. We consider a recently propo…

Particle Acceleration by Pickup Process Upstream of Relativistic Shocks

Masanori Iwamoto, Takanobu Amano, Yosuke Matsumoto +2

Particle acceleration at magnetized purely perpendicular relativistic shocks in electron-ion plasmas are studied by means of two-dimensional particle-in-cell simulations. Magnetize…

Electron Acceleration at Rippled Low-Mach-number Shocks in High-beta Collisionless Cosmic Plasmas

Oleh Kobzar, Jacek Niemiec, Takanobu Amano +4

Using large-scale fully-kinetic two-dimensional particle-in-cell simulations, we investigate the effects of shock rippling on electron acceleration at low-Mach-number shocks propag…
