Team led graduate student PPPL produces unique magnetic reconnection
2017/9/20
Jonathan Ng, a Princeton University graduate student at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), has for the first time applied a fluid simulation to the space...
Theory of magnetic reconnection in solar and astrophysical plasmas
Theory magnetic reconnection solar astrophysical plasmas
2012/2/23
Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this article we prese...
Particle Acceleration by Magnetic Reconnection in AGNs and in the IGM
Particle Acceleration Magnetic Reconnection AGNs IGM
2011/10/9
There is no single mechanism by which fast particles are accelerated in astrophysical environments, and it is now recognized that the data require a rich variety of different mechanisms operating unde...

High Lundquist Number Resistive MHD Simulations of Magnetic Reconnection: Searching for Secondary Island Formation
Lundquist Number Resistive MHD Simulations Magnetic Reconnection
2011/9/9
Recently, secondary island formation due to the tearing instability of the Sweet-Parker current sheet was identified as a possible mechanism that can lead to fast reconnection (less sensitive dependen...
The Internal-Collision-Induced Magnetic Reconnection and Turbulence (ICMART) Model of Gamma-Ray Bursts
gamma-rays burst general gamma-ray bursts individual GRB 080916C magnetic reconnection turbulence
2010/11/11
The recent Fermi observation of GRB 080916C shows that the bright photosphere emission associated with a putative fireball is missing, which suggests that the central engine likely launches a Poynting...
Jet deflection by very weak guide fields during magnetic reconnection
Jet deflection guide fields magnetic reconnection
2010/11/12
Simulations of antiparallel reconnection have shown collimated electron jets outflowing from the x-point, and associated highly elongated "outer electron diffusion regions." New PIC simulations with i...
New Insights into Dissipation in the Electron Layer During Magnetic Reconnection
New Insights Magnetic Reconnection Electron Layer
2010/3/8
Detailed comparisons are reported between laboratory observations of electron-scale dissipation layers near a reconnecting X-line and direct two-dimensional full-particle simulations. Many experimenta...
Evolution of magnetic helicity in the course of kinetic magnetic reconnection
magnetic helicity kinetic magnetic reconnection
2009/11/12
We investigate the evolution of magnetic helicity density in the course of 2D and 3D kinetic magnetic reconnection through thin current sheets. In 2D, the helicity density near a reconnection X-line b...
Evolution of magnetic helicity under kinetic magnetic reconnection:Part II B≠0 reconnection
magnetic helicity kinetic magnetic reconnection B≠0 reconnection
2009/11/12
We investigate the evolution of magnetic helicity under kinetic magnetic reconnection in thin current sheets. We use Harris sheet equilibria and superimpose an external magnetic guide field. Consequen...
Electrodynamics in a very thin current sheet leading to magnetic reconnection
thin current sheet magnetic reconnection
2009/11/9
We study the formation of a very thin current sheet (CS) and associated plasma electrodynamics using three-dimensional (3-D) particle-in-cell simulations with ion to electron mass ratio M/m=1836. The ...
