Ion Temperature Anisotropy Limits from Magnetic Curvature Scattering in Magnetotail Reconnection Jets
Louis Richard, Anton V. Artemyev, Cecilia Norgren +3
In collisionless plasmas, relaxation of the deviations of ion velocity distribution functions (VDFs) from local thermodynamic equilibrium occurs through particle interactions with…

Non-Maxwellianity of Ion Velocity Distributions in the Earth's Magnetosheath
Louis Richard, Sergio Servidio, Ida Svenningsson +6
We analyze the deviations from local thermodynamic equilibrium (LTE) of the ion velocity distribution function (iVDF) in collisionless plasma turbulence. Using data from the Magnet…

Eulerian and Lagrangian electron energization during magnetic reconnection
Konrad Steinvall, Louis Richard, Tünde Fülöp +2
Electron energization by magnetic reconnection has historically been studied in the Lagrangian guiding-center framework. Insights from such studies include that Fermi acceleration…
