Energy partitioning between thermal and non-thermal electrons and ions in magnetotail reconnection
Abhishek Rajhans, Mitsuo Oka, Marit Øieroset +9
Magnetic reconnection is an explosive energy release event. It plays an important role in accelerating particles to high non-thermal energies. These particles often exhibit energy…
Scaling of Particle Heating in Shocks and Magnetic Reconnection
Mitsuo Oka, Tai D. Phan, Marit Øieroset +4
Particles are heated efficiently through energy conversion processes such as shocks and magnetic reconnection in collisionless plasma environments. While empirical scaling laws for…
Relativistic Electron Acceleration and the 'Ankle' Spectral Feature in Earth's Magnetotail Reconnection
Weijie Sun, Mitsuo Oka, Marit Øieroset +14
Electrons are accelerated to high, non-thermal energies during explosive energy-release events in space, such as magnetic reconnection. However, the properties and acceleration mec…
Maximum Energy of Particles in Plasmas
Mitsuo Oka, Kazuo Makishima, Toshio Terasawa
Particles are accelerated to very high, non-thermal energies in space, solar, and astrophysical plasma environments. In cosmic ray physics, the "Hillas limit" is often used as a ro…
Electron Power-Law Spectra in Solar and Space Plasmas
M. Oka, J. Birn, M. Battaglia +10
Particles are accelerated to very high, non-thermal energies in solar and space plasma environments. While energy spectra of accelerated electrons often exhibit a power law, it rem…
Radiation from relativistic shocks with turbulent magnetic fields
K. -I. Nishikawa, J. Niemiec, M. Medvedev +10
Using our new 3-D relativistic electromagnetic particle (REMP) code parallelized with MPI, we investigated long-term particle acceleration associated with a relativistic electron-p…
