Fast Inverse Transform Sampling of Non‐Gaussian Distribution Functions in Space Plasmas [PDF]
Journal of Geophysical Research: Space Physics, 2022 Non‐Gaussian distributions are commonly observed in collisionless space plasmas. Generating samples from non‐Gaussian distributions is critical for the initialization of particle‐in‐cell simulations that investigate their driven and undriven dynamics. To

The two-fluid dynamics and energetics of the asymmetric magnetic reconnection in laboratory and space plasmas. [PDF]
Nat Commun, 2018 Magnetic reconnection is a fundamental process in magnetized plasma where magnetic energy is converted to plasma energy. Despite huge differences in the physical size of the reconnection layer, remarkably similar characteristics are observed in both ...

DRAFT: A Method for Wave Analyses in Space Plasmas
Astrophysical Journal, 2022 In this study, we apply a method for wave analyses in space plasmas, to better understand the nature of plasma waves and turbulence. Such a method is based on four-spacecraft measurements of magnetic fields or electric fields; it calculates the phase ...

Kappa distributions: Thermodynamic origin and Generation in space plasmas [PDF]
Journal of Physics: Conference Series, 2018 The paper reviews the new developments on the thermodynamic origin of kappa distributions and their generation in space plasmas. We present the correct formulation of kappa distributions that is consistent with thermodynamics.

On the Calculation of the Effective Polytropic Index in Space Plasmas [PDF]
Entropy (Basel), 2019 The polytropic index of space plasmas is typically determined from the relationship between the measured plasma density and temperature. In this study, we quantify the errors in the determination of the polytropic index, due to uncertainty in the ...

On the violation of the zeroth law of turbulence in space plasmas [PDF]
Journal of Plasma Physics, 2020 The zeroth law of turbulence states that, for fixed energy input into large-scale motions, the statistical steady state of a turbulent system is independent of microphysical dissipation properties. This behaviour, which is fundamental to nearly all fluid-

The cosmic ray-driven streaming instability in astrophysical and space plasmas
Physics of Plasmas, 2021 Energetic non-thermal particles, or cosmic rays, are a major component of astrophysical plasmas next to magnetic fields, radiation, and thermal gas.

Electromagnetic ion cyclotron instability stimulated by the suprathermal ions in space plasmas: A quasi-linear approach [PDF]
Physics of Plasmas, 2020 In collision-poor space plasmas, protons with an excess of kinetic energy or temperature in the direction perpendicular to the background magnetic field can excite the electromagnetic ion cyclotron (EMIC) instability.

Relationship between Polytropic Index and Temperature Anisotropy in Space Plasmas [PDF]
, 2020 The paper develops a theoretical relationship between the polytropic index and the temperature anisotropy that may characterize space plasmas. The derivation is based on the correlation among the kinetic energies of particles with velocities described by

Electromagnetic Ion–Ion Instabilities in Space Plasmas: Effects of Suprathermal Populations [PDF]
Astrophysical Journal, 2020 In collision-poor plasmas from space, three distinct ion–ion instabilities can be driven by the proton beams streaming along the background magnetic field: left-hand resonant, nonresonant, and right-hand resonant instabilities. These instabilities are in
