Electron and Proton Acceleration in Trans-relativistic Magnetic Reconnection: Dependence on Plasma Beta and Magnetization [PDF]

Astrophysical Journal, 2018
Nonthermal electron acceleration via magnetic reconnection is thought to play an important role in powering the variable X-ray emission from radiatively inefficient accretion flows around black holes.

Super-efficient Electron Acceleration by an Isolated Magnetic Reconnection

Astrophysical Journal, 2019
Magnetic reconnection—the process typically lasting for a few seconds in space—is able to accelerate electrons. However, the efficiency of the acceleration during such a short period is still a puzzle.

Prevalence of magnetic reconnection in the near-Sun heliospheric current sheet

Astronomy & Astrophysics, 2020
During three of its first five orbits around the Sun, Parker Solar Probe (PSP) crossed the large-scale heliospheric current sheet (HCS) multiple times and provided unprecedented detailed plasma and field observations of the near-Sun HCS.
