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 …

The auroral oval is a well-established concept, introduced more than five decades ago. The
Alfvénic oval, on the other hand, is a very recent concept, which has been revealed in both …

Substorms release a large amount of energy, some of which is used to energize the
precipitating particles in the polar region. Superposed epoch analysis was performed with …

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 …

Juno satellite observations have illustrated substantial examples of broadband electron
energization up to 105–106 eV levels. In order to explain these observations, we use a …

General methods for improving the specification of electron precipitation in global
simulations are described and implemented in the Lyon‐Fedder‐Mobarry (LFM) global …

Extremely bright aurora was witnessed in East Asia on 17 September 1770, according to
historical documents. The aurora was described as “as bright as a night with full moon” at …

Results from 1D Vlasov drift-kinetic plasma simulations reveal how and where auroral
electrons are accelerated along Earth's geomagnetic field. In the warm plasma sheet …

The Juno spacecraft in a polar orbit around Jupiter has observed broadband electron
energization signatures at high latitudes (Mauk et al., 2017, https://doi. org/10.1038 …

A new 2‐D self‐consistent hybrid gyrofluid‐kinetic electron model in dipolar coordinates is
presented and used to simulate dispersive‐scale Alfvén wave pulse propagation from the …
