3D Space-Time Adaptive Hybrid Simulations of Magnetosheath High-Speed Jets
(American Geophysical Union, 2021-06-18)
Abstract
We study the generation and evolution of spatially localized dynamic plasma pressure enhancements in the magnetosheath (high-speed jets) by carrying out three-dimensional hybrid simulations of the Earth's dayside ...
Self-organisation Processes In The Carbon ARC For Nanosynthis
(US Department of Energy Office of Scientific and Technical Information, 2014-02-26)
The atmospheric pressure carbon arc in inert gases such as helium is an important method for the production of nanomaterials. It has recently been shown that the formation of the carbon deposit on the cathode from gaseous ...
A Case Study of Nonresonant Mode 3-s ULF Waves Observed by MMS
(American Geophysical Union, 2020-11-16)
The nature of the 3-s ultralow frequency (ULF) wave in the Earth's foreshock region and the associated wave-particle interaction are not yet well understood. We investigate the 3-s ULF waves using Magnetospheric Multiscale ...
Reconstruction of Electron and Ion Distribution Functions in a Magnetotail Reconnection Diffusion Region
(American Geophysical Union, 2020-05-23)
In the diffusion region of magnetotail reconnection, particle distributions are highly structured, exhibiting triangular shapes and multiple striations that deviate dramatically from the Maxwellian distribution. Fully ...
Solitary Magnetic Structures at Quasi-Parallel Collisionless Shocks: Formation
(American Geophysical Union, 2020-12-11)
Abstract
Solitary magnetic structures known as SLAMS (short large-amplitude magnetic structures) have been considered as essential elements of collisionless shocks with quasi-parallel geometries. Yet the physics underlying ...
Magnetopause Reconnection and Indents Induced by Foreshock Turbulence
(American Geophysical Union, 2021-05-31)
Abstract
Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth-sized indents. Both the interplanetary magnetic field (IMF) and ...
On the rate of energy deposition by an ion ring velocity beam
(AIP Publishing, 2021-05-03)
Using a novel three-dimensional electromagnetic hybrid code, XHYPERS, we simulate the generation of lower hybrid oscillations in a magnetized plasma by a heavy ion beam with a ring-shaped velocity distribution over much ...
Lower-Hybrid-Drift Vortices in the Electron-Scale Magnetic Reconnection Layer
(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
(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 ...
An Extended MHD Study of the 16 October 2015 MMS Diffusion Region Crossing
(American Geophysical Union, 2019-09-09)
The Magnetospheric Multiscale (MMS) mission has given us unprecedented access to high cadence particle and field data of magnetic reconnection at Earth's magnetopause. MMS first passed very near an X-line on 16 October ...
