Lower-Hybrid-Drift Vortices in the Electron-Scale Magnetic Reconnection Layer

Ng, Jonathan; Chen, L.-J.; Le, A.; Stanier, A.; Wang, S.; Bessho, N. (American Geophysical Union, 2020-11-10)

Abstract Lower-hybrid-drift waves driving vortical flows have recently been discovered in the electron current layer during magnetic reconnection in the terrestrial magnetotail. Yet, spacecraft measurements cannot address ...

Kinetic Structure of the Electron Diffusion Region in Antiparallel Magnetic Reconnection

Ng, Jonathan; Egedal, J.; Le, A.; Daughton, W.; Chen, L.-J. (American Physical Society, 2011-02-10)

Strong electron pressure anisotropy has been observed upstream of electron diffusion regions during reconnection in Earth’s magnetotail and kinetic simulations. For collisionless antiparallel reconnection, we find that the ...

Three-dimensional stability of current sheets supported by electron pressure anisotropy

Le, A.; Stanier, A.; Daughton, W.; Ng, Jonathan; Egedal, J.; Nystrom, W. D.; Bird, R. (AIP Publishing, 2019-10-17)

The stability of electron current sheets embedded within the reconnection exhaust is studied with a 3D fully kinetic particle-in-cell simulation. The electron current layers studied here form self-consistently in a ...

Phase space structure of the electron diffusion region in reconnection with weak guide fields

Ng, Jonathan; Egedal, J.; Le, A.; Daughton, W. (AIP Publishing, 2012-11-12)

Kinetic simulations of magnetic reconnection provide detailed information about the electric and magnetic structure throughout the simulation domain, as well as high resolution profiles of the essential fluid parameters ...

Current sheets and pressure anisotropy in the reconnection exhaust

Le, A.; Egedal, J.; Ng, Jonathan; Karimabadi, H.; Scudder, J.; Roytershteyn, V.; Daughton, W.; Liu, Y.-H. (AIP Publishing, 2014-01-14)

A particle-in-cell simulation shows that the exhaust during anti-parallel reconnection in the collisionless regime contains a current sheet extending 100 inertial lengths from the X line. The current sheet is supported by ...

The role of guide field in magnetic reconnection driven by island coalescence

Stanier, A.; Daughton, W.; Simakov, Andrei N.; Chacón, L.; Le, A.; Karimabadi, H.; Ng, Jonathan; Bhattacharjee, A. (AIP Publishing, 2017-02-24)

A number of studies have considered how the rate of magnetic reconnection scales in large and weakly collisional systems by the modelling of long reconnecting current sheets. However, this set-up neglects both the formation ...

Pressure Tensor Elements Breaking the Frozen-In Law During Reconnection in Earth’s Magnetotail

Egedal, J.; Ng, Jonathan; Le, A.; Daughton, W.; Wetherton, B.; Dorelli, J.; Gershman, D.; Rager, A. (American Physical Society, 2019-11-25)

Aided by fully kinetic simulations, spacecraft observations of magnetic reconnection in Earth’s magnetotail are analyzed. The structure of the electron diffusion region is in quantitative agreement with the numerical model. ...
