Electrostatic solitary waves (ESWs) are characterized by localized bipolar electric fields
parallel to the magnetic field and are frequently observed in space plasmas. In this paper a …

Direct measurements of parallel electric fields suggest that they are, in part, self-consistently
supported as strong double layers in the auroral downward current region. The observed …

Investigating the process of electron acceleration in auroral regions, we present a study of
the temporal evolution of the interaction of Alfvén waves (AW) with a plasma …

In this paper, electromagnetic emissions produced in a thin beam-plasma system are
studied using two-dimensional particle-in-cell simulations. For the first time, the problem of …

We present a statistical analysis of more than 2,400 electrostatic solitary waves interpreted
as electron holes (EH) measured aboard at least three Magnetospheric Multiscale (MMS) …

A model is presented for a new type of fast solitary waves which is observed in downward
current regions of the auroral zone. The three-dimensional, coherent structures are …

Phase‐space electron holes are seen in simulations, laboratory plasmas, and many regions
of the Earth's space environment. We present simulations of beam plasmas showing that the …

We study formation process of electrostatic solitary waves (ESW) observed by recent
spacecraft via one‐and two‐dimensional electrostatic particle simulations with open …

We use a new nonlinear guiding center particle in cell code to investigate the role of Alfvén
waves in the auroral particle acceleration. The propagation of an Alfvén wave in an …

Electron phase space holes or vortices (EHs) are electrostatic solitary waves with a bipolar
parallel (magnetic field-aligned) electric field. They are formed in a nonlinear stage of …
