Discovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958
was the first major discovery of the Space Age. The observation of distinct inner and outer …

The past decade transformed our observational understanding of energetic particle
processes in near‐Earth space. An unprecedented suite of observational systems was in …

The flux of energetic electrons in the Earth's outer radiation belt can vary by several orders of
magnitude over time scales less than a day, in response to changes in properties of the …

The Exploration of energization and Radiation in Geospace (ERG) project aims to study
acceleration and loss mechanisms of relativistic electrons around the Earth. The Arase …

Local acceleration is required to explain electron flux increases in the outer Van Allen
radiation belt during magnetic storms. Here we show that fast magnetosonic waves …

We investigate the wave magnetic field data from three THEMIS spacecraft over the recent
31 months to perform a statistical study of equatorial magnetosonic (MS) wave properties …

Fast magnetosonic waves can lead to the local acceleration of electrons from∼ 10 keV up to
a few MeV on a timescale of 1–2 d and may play an important role in radiation belt …

We investigate the importance of electron scattering by magnetosonic waves in the Earth's
inner magnetosphere. A statistical survey of the magnetosonic wave amplitude and wave …

Recent analysis using quasilinear theory (QLT) has shown that magnetosonic (MS) waves
are able to accelerate electrons to relativistic energies on fast time scales (∼ 1 day) …

Recent observations show that the decay rate of relativistic electrons measured at low
altitudes in the slot region at L= 2 is an order of magnitude shorter than theoretical estimates …
