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 …

The Earth's magnetotail is an extremely complex system which—energized by the solar wind—
displays many phenomena, and Alfvén waves are essential to its dynamics. While Alfvén …

Observations from the FAST satellite are used to create a model for dispersive Alfvén waves
above the auroral oval. Using this model, it is shown how these waves may accelerate …

More than half a century after the discovery of Pi2 pulsations, Pi2 research is still vigorous
and evolving. Especially in the last decade, new results have provided supporting evidence …

We report in situ observations from the Cluster and FAST spacecraft showing the deposition
of energy into the auroral ionosphere from broadband ULF waves in the cusp and low …

It is demonstrated from observations that the Alfvénic aurora may be powered by a turbulent
cascade transverse to the geomagnetic field from large MHD scales to small Alfvén wave …

The magnetotail is the main source of energetic electrons for Earth's inner magnetosphere.
Electrons are adiabatically heated during flow bursts (rapid earthward motion of the plasma) …

Using observations from the FAST small explorer spacecraft, we present fields and plasma
observations above the dayside auroral oval showing the erosion of ionospheric plasmas …

A prominent yet largely unrecognized feature of the inner magnetosphere associated with
particle injections, and more generally geomagnetic storms, is the occurrence of broadband …

In this paper we study the interaction of kinetic Alfven waves generated near the equatorial
plane of the magnetosphere with electrons having initial energies up to∼ 100 eV. Wave …
