Energy Exchange Between Electromagnetic Ion Cyclotron (EMIC) Waves and Thermal Plasma: From Theory to Observations

Frontiers in Astronomy and Space Sciences, 2021
The cold plasmaspheric plasma, the ring current and the radiation belts constitute three important populations of the inner magnetosphere. The overlap region between these populations gives rise to wave-particle interactions between different plasma ...

EMIC wave parameterization in the long‐term VERB code simulation [PDF]

Journal of Geophysical Research: Space Physics, 2017
AbstractElectromagnetic ion cyclotron (EMIC) waves play an important role in the dynamics of ultrarelativistic electron population in the radiation belts. However, as EMIC waves are very sporadic, developing a parameterization of such wave properties is a challenging task.

Properties of EMIC Waves and EMIC Wave‐Driven Electron Precipitation in Subauroral Latitudes Observed at Athabasca, Canada

Journal of Geophysical Research: Space Physics
AbstractElectromagnetic ion cyclotron (EMIC) waves are believed to cause the loss of relativistic electrons from the outer radiation belt into the atmosphere due to pitch angle scattering. However, it is still unclear whether all EMIC waves can scatter relativistic electrons or which conditions are favorable for pitch angle scattering by EMIC waves. In

The modulation of electromagnetic ion cyclotron waves by Pc 5 ULF waves [PDF]

Annales Geophysicae, 2009
The modulation of electromagnetic ion cyclotron (EMIC) waves by longer-period ULF waves has been proposed as a method for producing pearl structured Pc 1–2 EMIC waves.

Direct Evidence of the Pitch Angle Scattering of Relativistic Electrons Induced by EMIC Waves

Geophysical Research Letters, 2020
In this study, we analyze an electromagnetic ion cyclotron (EMIC) wave event of rising tone elements recorded by the Van Allen Probes. The pitch angle distributions of relativistic electrons exhibit a direct response to the two elements of EMIC waves: at

EMIC waves observed by Cluster near the plasmapause

Journal of Geophysical Research: Space Physics, 2013
AbstractWe analyze a long‐duration electromagnetic ion cyclotron (EMIC) wave event seen in the inner magnetosphere in order to understand the propagation characteristics of these waves in the vicinity of the plasmapause. The study takes advantage of the south to north orbit of the four‐satellite Cluster constellation as it passed through perigee at L ~

High-resolution in situ observations of electron precipitation-causing EMIC waves [PDF]

, 2015
Electromagnetic ion cyclotron (EMIC) waves are thought to be important drivers of energetic electron losses from the outer radiation belt through precipitation into the atmosphere. While the theoretical possibility of pitch angle scattering-driven losses

Interaction of Inner Heliosheath Ions with Electromagnetic Ion Cyclotron Waves

The Astrophysical Journal, 2023
Inner heliosheath (IHS) ions are expected to be exposed to various waves, shocks, and turbulence, which can affect ion distributions and thus their charge-exchange rates with interstellar neutral atoms.

‘From the Fields Into the Bars’: The Story of Israel's First Transgender Novel, The Cut (1977)

Gender &History, EarlyView.
ABSTRACT In 1977, an Israeli transgender woman, Judy Spotheim, published an autobiographical novel entitled The Cut. It describes the emergence of a trans community in the commercial‐sex areas of Tel Aviv‐Jaffa, hoping to humanise trans women (coccinelles). This article is the first to study the novel and present a biography of Spotheim.
