Reconnection-induced electron energization in magnetospheric Kelvin-Helmholtz dynamics
Silvia Ferro, Fabio Bacchini, Giuseppe Arrò +2
The Kelvin-Helmholtz instability (KHI) is a major driver of multiscale plasma dynamics at velocity shear layers, where it can promote the formation of current sheets and the onset…
Fast Magnetosonic Turbulence in Two-Dimensional Relativistic Plasmas
Petr Ugarov, Vladimir Zhdankin, Giuseppe Arrò
We present fully kinetic simulations of driven 2D turbulence in a relativistic plasma, designed for the first time to induce a fast magnetosonic cascade. As the driving strength in…
Plasma Mixing Driven by the Collisionless Kelvin-Helmholtz Instability: Insights from fully kinetic simulation and density-based diagnostics
Silvia Ferro, Fabio Bacchini, Giuseppe Arrò +2
Simulations and observations of the low-latitude magnetosphere-magnetosheath boundary layer indicate that the Kelvin-Helmholtz instability (KHI) drives vortex structures that enhan…
Electron neural closure for turbulent magnetosheath simulations: energy channels
George Miloshevich, Luka Vranckx, Felipe Nathan de Oliveira Lopes +3
In this work, we introduce a non-local five-moment electron pressure tensor closure parametrized by a Fully Convolutional Neural Network (FCNN). Electron pressure plays an importan…
Anisotropic Heating and Parallel Heat Flux in Electron-only Magnetic Reconnection with Intense Guide Fields
Jincai Ren, Giuseppe Arrò, Maria Elena Innocenti +1
Electron-only reconnection is a process recently observed in the Earth's magnetosheath, where magnetic reconnection occurs at electron kinetic scales with only electrons involved.…
Generation of sub-ion scale magnetic holes from electron shear flow instabilities in plasma turbulence
Giuseppe Arrò, Francesco Pucci, Francesco Califano +2
Magnetic holes (MHs) are coherent structures associated with strong magnetic field depressions in magnetized plasmas. They are observed in many astrophysical environments at a wide…
Spectral properties and energy transfer at kinetic scales in collisionless plasma turbulence
Giuseppe Arrò, Francesco Califano, Giovanni Lapenta
By means of a fully kinetic simulation of freely decaying plasma turbulence, we study the spectral properties and the energy exchanges characterizing the turbulent cascade in the k…
Statistical Properties of Turbulent Fluctuations Associated with Electron-only Magnetic Reconnection
Giuseppe Arrò, Francesco Califano, Giovanni Lapenta
Context: Recent satellite measurements in the turbulent magnetosheath of Earth have given evidence of an unusual reconnection mechanism that is driven exclusively by electrons. Thi…
