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…

Interaction of the Prominence Plasma within the Magnetic Cloud of an ICME with the Earth's Bow Shock

Hadi Madanian, Li-Jen Chen, Jonathan Ng +5

The magnetic cloud within an interplanetary coronal mass ejection (ICME) is characterized by high magnetic field intensities. In this study, we investigate the interaction of a mag…
