A firehose-like aperiodic instability of counter-beaming electron plasmas
(IOP Publishing, 2020)
Depending on the physical conditions involved, beam plasma systems may reveal new unstable regimes triggered by wave instabilities of different natures. We show through linear theory and numerical simulations the existence ...
Linear kinetic waves in plasmas described by Kappa Distributions
(Elsevier, 2017)
In this chapter we present an overview of the excitation, propagation, and
absorption of linear plasma waves in collisionless, spatially uniform, multicomponent,
magnetized non-Maxwellian plasma characterized by a ...
Particle-in-cell Simulations of Firehose Instability Driven by Bi-Kappa Electrons
(Institute of Physics Publishing, 2019)
We report the first results from particle-in-cell simulations of the fast-growing aperiodic electron firehose instability driven by the anisotropic bi-Kappa distributed electrons. Such electrons characterize space plasmas, ...
Electromagnetic fluctuations of the whistler-cyclotron and firehose instabilities in a Maxwellian and Tsallis-kappa-like plasma
(American Geophysical Union, 2015)
Observed electron velocity distributions in the Earth's magnetosphere and the solar wind exhibit a variety of nonthermal features which deviate from thermal equilibrium, for example, in the form of temperature anisotropies, ...
Turbulence in collisionless plasmas: statistical analysis from numerical simulations with pressure anisotropy
(IOP PUBLISHING LTD, 2011)
In recent years, we have experienced increasing interest in the understanding of the physical properties of collisionless plasmas, mostly because of the large number of astrophysical environments (e. g. the intracluster ...
PIC Simulations of Velocity-space Instabilities in a Decreasing Magnetic Field: Viscosity and Thermal Conduction
(Institute of Physics Publishing, 2018)
We use particle-in-cell (PIC) simulations of a collisionless, electron–ion plasma with a decreasing background
magnetic field, B, to study the effect of velocity-space instabilities on the viscous heating and thermal ...
PIC simulations of velocity space instabilities in a decreasing magnetic field: viscosity and thermal conduction
(IOP Publishing Ltd, 2018)
We use particle-in-cell (PIC) simulations of a collisionless, electron-ion plasma with a decreasing background magnetic field, B, to study the effect of velocity-space instabilities on the viscous heating and thermal ...
SOLAR WIND MAGNETIC FLUCTUATIONS and ELECTRON NON-THERMAL TEMPERATURE ANISOTROPY: SURVEY of WIND-SWE-VEIS OBSERVATIONS
(Institute of Physics Publishing, 2016)
© 2016. The American Astronomical Society. All rights reserved. The solar wind electron velocity distribution function (eVDF) exhibits a variety of non-thermal features that deviate from thermal equilibrium. These deviations ...
Spontaneous magnetic fluctuations and collisionless regulation of turbulence in the earth's magnetotail
(IOP, 2022)
Among the fundamental and most challenging problems of laboratory, space, and astrophysical plasma physics is
to understand the relaxation processes of nearly collisionless plasmas toward quasi-stationary states and ...
Features of collisionless turbulence in the intracluster medium from simulated Faraday rotation maps - II. The effects of instabilities feedback
(Oxford University Press, 2017-03)
Statistical analysis of Faraday rotation measure (RM) maps of the intracluster medium (ICM) of galaxy clusters provides a unique tool to evaluate some spatial features of the magnetic fields there. Its combination with ...
