Two-Dimensional particle-in-cell simulations of the nonresonant, cosmic-ray driven instability in SNR shocks
Yutaka Ohira, Brian Reville, John G. Kirk +1
In supernova remnants, the nonlinear amplification of magnetic fields upstream of collisionless shocks is essential for the acceleration of cosmic rays to the energy of the "knee"…

Oblique Ion Two-Stream Instability in the Foot Region of a Collisionless Shock
Yutaka Ohira, Fumio Takahara
Electrostatic behavior of a collisionless plasma in the foot region of high Mach number perpendicular shocks is investigated through the two-dimensional linear analysis and electro…

Absence of Electron Surfing Acceleration in a Two-Dimensional Simulation
Yutaka Ohira, Fumio Takahara
Electron acceleration in high Mach number perpendicular shocks is investigated through two-dimensional electrostatic particle-in-cell (PIC) simulation. We simulate the shock foot r…
