Journal ArticleDOI
Geospace Environmental Modeling (GEM) magnetic reconnection challenge
Joachim Birn,James Drake,Michael Shay,Barrett Rogers,Richard E. Denton,Michael Hesse,M. Kuznetsova,Zhiwei Ma,Amitava Bhattacharjee,Antonius Otto,P. L. Pritchett +10 more
TL;DR: In this paper, a simple Harris sheet configuration with a specified set of initial conditions, including a finite amplitude, magnetic island perturbation to trigger the dynamics of magnetic reconnection is studied.
Journal ArticleDOI
Fast reconnection in high-Lundquist-number plasmas due to the plasmoid Instability
TL;DR: In this article, the scaling of the growth rate of the most rapidly growing plasmoid instability with respect to the Lundquist number is shown to follow from the classical dispersion relation for tearing modes.
Journal ArticleDOI
Fast Reconnection in High-Lundquist-Number Plasmas Due to Secondary Tearing Instabilities
TL;DR: In this paper, the scaling of the growth rate of the fastest growing instability with respect to the Lundquist number is shown to follow from the classical dispersion relation for tearing modes.
Journal ArticleDOI
Scaling laws of resistive magnetohydrodynamic reconnection in the high-Lundquist-number, plasmoid-unstable regime
TL;DR: Loureiro et al. as discussed by the authors showed that the number of plasmoids in a system that exceeds a critical value of the Lundquist number (S) is unstable to the plasmoid instability.
Journal ArticleDOI
Observation of energetic electrons within magnetic islands
Li-Jen Chen,Amitava Bhattacharjee,P. A. Puhl-Quinn,H. Yang,Naoki Bessho,Shinsuke Imada,S. Mühlbachler,P. W. Daly,Bertrand Lefebvre,Yuri V. Khotyaintsev,Andris Vaivads,Andrew Fazakerley,E. Georgescu +12 more
TL;DR: In this article, the first evidence of the link between energetic electrons and magnetic islands during reconnection in the Earth's magnetosphere was reported, which suggests that energetic electron fluxes peak at sites of compressed density within islands, which imposes a new constraint on theories of electron acceleration.
