Almost 40 years ago the concept of the substorm current wedge was developed to explain
the magnetic signatures observed on the ground and in geosynchronous orbit during …

This paper deals with acceleration processes in the magnetotail and the processes that
enhance particle precipitation from the tail into the ionosphere through electric fields in the …

A review of the present status of the theory of magnetic reconnection is given. In strongly
collisional plasmas reconnection proceeds via resistive current sheets, ie quasi-stationary …

The present 15th volume of the ISSI Space Science Series is devoted to Auroral Plasma
Physics. The aurora is arguably the most intriguing phenomenon in space plasma physics …

Using three‐dimensional MHD simulations of magnetic reconnection in the magnetotail, we
investigate the fate of earthward bursty bulk flows (BBFs). The flow bursts are identified as …

Earthward flow bursts associated with small auroral expansions, including pseudobreakups,
and auroral streamers are studied by using Geotail plasma and magnetic field data and …

Using the electromagnetic fields of a recent MHD simulation of magnetotail reconnection,
flow bursts and dipolarization, we investigate the acceleration of test particles (protons and …

Recent models of magnetotail activity have associated the braking of earthward flow with
dipolarization and the reduction and diversion of cross‐tail current, that is, the signatures of …

The substorm‐associated behavior of the thermal plasma (30eV< E< 40keV) in the plasma
sheet is examined by means of a superposed epoch analysis, using a full year of data from a …

The goal of the present study is to observationally test the idea that the substorm current
wedge (SCW) is an ensemble of wedgelets, mesoscale current systems that correspond to …
