Magnetic field turbulence in the solar wind at sub-ion scales: in situ observations and numerical simulations
L. Matteini, L. Franci, O. Alexandrova +5
We investigate the transition of the solar wind turbulent cascade from MHD to sub-ion range by means of a detail comparison between in situ observations and hybrid numerical simula…
Whistler Waves and Electron Properties in the Inner Heliosphere: Helios Observations
Vamsee Krishna Jagarlamudi, Olga Alexandrova, Laura Bercic +4
We present the analysis of narrowband whistler wave signatures observed in the inner heliosphere (0.3-1 au). These signatures are bumps in the spectral density in the 10-200 Hz fre…
Observational quantification of three-dimensional anisotropies and scalings of space plasma turbulence at kinetic scales
Tieyan Wang, Jiansen He, Olga Alexandrova +2
A statistical survey of spectral anisotropy of space plasma turbulence is performed using five years measurements from MMS in the magnetosheath. By measuring the five-point second-…
Kinetic turbulence in space plasmas observed in the near-Earth and near-Sun solar wind
Olga Alexandrova, Vamsee Krishna Jagarlamudi, Claudia Rossi +4
Turbulence develops in any stressed flow when the scales of the forcing are much larger than those of the dissipation. In neutral fluids, it consists of chaotic motions in physical…
A Case for Electron-Astrophysics
Daniel Verscharen, Robert T. Wicks, Olga Alexandrova +27
A grand-challenge problem at the forefront of physics is to understand how energy is transported and transformed in plasmas. This fundamental research priority encapsulates the con…
Magnetospheric Multiscale Observation of Kinetic Signatures in the Alfvén Vortex
Tieyan Wang, Olga Alexandrova, Denise Perrone +9
Alfvén vortex is a multi-scale nonlinear structure which contributes to intermittency of turbulence. Despite previous explorations mostly on the spatial properties of the Alfvén vo…
