Laboratory Space Physics: Investigating the Physics of Space Plasmas in the Laboratory [PDF]

open access: yesPhysics of Plasmas, 2018
Laboratory experiments provide a valuable complement to explore the fundamental physics of space plasmas without the limitations inherent to spacecraft measurements. Specifically, experiments overcome the restriction that spacecraft measurements are made

On the violation of the zeroth law of turbulence in space plasmas [PDF]

open access: yesJournal 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

open access: yesPhysics 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]

open access: yesPhysics 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.

On the Existence of Subsonic Solitary Waves Associated with Reconnection Jets in Earth’s Magnetotail

open access: yesThe Astrophysical Journal, 2023
The Magnetospheric Multiscale Spacecraft (MMS) has detected the signature of electrostatic solitary waves (ESWs) occurring in the reconnection jet site of the Earth’s magnetotail (Liu et al.). These observations have motivated us to explore the mechanism

Relationship between Polytropic Index and Temperature Anisotropy in Space Plasmas [PDF]

open access: yes, 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]

open access: yesAstrophysical 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

Direct Observations of Reconnection Fronts in Earth's Turbulent Magnetosheath

open access: yesThe Astrophysical Journal, 2023
Reconnection fronts (RFs), ion-scale magnetic transients characterized by dramatic enhancement of reconnected magnetic fields, have been documented as crucial energy transfer regions during magnetic reconnection.

Successive Energy Conversion at a Stepwise Dipolarization Front

open access: yesThe Astrophysical Journal, 2023
Dipolarization fronts (DFs), ion-scale magnetic structures characterized by sharp enhancement of northward magnetic field developed within plasma jets, have been suggested to play a crucial role in the energy transfer chain in the terrestrial magnetotail.
