Assessing the Feasibility of Cosmic-Ray Acceleration by Magnetic Turbulence at the Galactic Center
Feasibility Cosmic-Ray Acceleration Magnetic Turbulence the Galactic Center
2012/2/23
The presence of relativistic particles at the center of our galaxy is evidenced by the diffuse TeV emission detected from the inner $\sim$$2^\circ$ of the Galaxy. Although it is not yet entirely clear...
Radiative diagnostics for sub-Larmor scale magnetic turbulence
Radiative diagnostics sub-Larmor scale magnetic turbulence
2011/9/6
Radiative diagnostics of high-energy density plasmas is addressed in this paper. We propose that the radiation produced by energetic particles in small-scale magnetic field turbulence, which can occur...
A model of driven and decaying magnetic turbulence in a cylinder
model Driven field-aligned currents
2011/8/30
Using mean-field theory, we compute the evolution of the magnetic field in a cylinder with outer perfectly conducting boundaries, an imposed axial magnetic and electric field. The thus injected magnet...
The Effect of Magnetic Turbulence Energy Spectra and Pickup Ions on the Heating of the Solar Wind
Pickup ions, Solar wind heating, MHD turbulence, Wave-particle interaction
2011/9/9
In recent years, a phenomenological solar wind heating model based on a turbulent energy cascade prescribed by the Kolmogorov theory has produced reasonably good agreement with observations on proton ...
Numerical simulation of ion dynamics in the magnetotail magnetic turbulence:On collisionless conductivity
Numerical simulation ion dynamics magnetotail magnetic turbulence collisionless conductivity
2009/11/13
The ion dynamics in the distant Earth's magnetotail is studied in the case that a cross tail electric field and reconnection parity magnetic turbulence are present in the neutral sheet. A test particl...
Magnetic turbulence in and around the Earth's magnetosphere
Magnetic turbulence Earth's magnetosphere
2009/5/27
Magnetic turbulence is found in most space plasmas, including the geospace environment. Recent spacecraft observations of magnetic turbulence in the ion foreshock, in the magnetosheath, in the polar ...
