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 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...

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...
