Numerical Tests of Fast Reconnection in Weakly Stochastic Magnetic Fields [PDF]

, 2009
We study the effects of turbulence on magnetic reconnection using 3D numerical simulations. This is the first attempt to test a model of fast magnetic reconnection in the presence of weak turbulence proposed by Lazarian & Vishniac (1999).

Turbulent Reconnection Acceleration

The Astrophysical Journal, 2022
Abstract The ubiquitous turbulence in astrophysical plasmas is important for both magnetic reconnection and reconnection acceleration. We study the particle acceleration during fast 3D turbulent reconnection with reconnection-driven turbulence.

Transition from ion-coupled to electron-only reconnection: Basic physics and implications for plasma turbulence [PDF]

Physics of Plasmas, 2019
Using kinetic particle-in-cell (PIC) simulations, we simulate reconnection conditions appropriate for the magnetosheath and solar wind, i.e., plasma beta (ratio of gas pressure to magnetic pressure) greater than 1 and low magnetic shear (strong guide ...

Identifying the electron diffusion region in a realistic simulation of Earth's magnetotail

Geophysical Research Letters, 2016
A historic challenge to understanding geomagnetic activity is determining where in Earth's magnetotail magnetic energy is converted into particle energy and heat by magnetic reconnection.

Theory and Applications of Non-Relativistic and Relativistic Turbulent Reconnection

, 2015
Realistic astrophysical environments are turbulent due to the extremely high Reynolds numbers. Therefore, the theories of reconnection intended for describing astrophysical reconnection should not ignore the effects of turbulence on magnetic reconnection.

Magnetic-reconnection-driven Turbulence and Turbulent Reconnection Acceleration

The Astrophysical Journal, 2023
Abstract This paper employs an MHD-PIC method to perform numerical simulations of magnetic-reconnection-driven turbulence and turbulent reconnection acceleration of particles. Focusing on the dynamics of the magnetic reconnection, the properties of self-driven turbulence, and the behavior of particle acceleration, we find the following: (

Waves Generated by Electron Beam in a Crater-Shaped Flux Rope

Frontiers in Physics, 2021
Understanding the nature and characteristics of high-frequency waves inside a flux rope may be important as the wave-particle interaction is important for charged-particle energization and the ensuing dissipation process. We analyze waves generated by an

Relationship Between Geomagnetic Storms and Auroral/Magnetospheric Substorms: Early Studies

Frontiers in Astronomy and Space Sciences, 2020
This paper describes a short story of how I learned in early days in space physics (1960–1970) that there are the direct and feed-back relationships between geomagnetic storms and auroral/magnetospheric substorms.

Juno Observations of Ion‐Inertial Scale Flux Ropes in the Jovian Magnetotail

Geophysical Research Letters, 2021
Two ion‐inertial scale magnetic flux ropes are identified in the Juno magnetic field measurements in the dawnside Jovian magnetotail. Previously reported plasmoids in this region had typical diameters of several Jovian radii (RJ).
