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.

MMS Observations of Harmonic Electromagnetic Ion Cyclotron Waves [PDF]
Geophysical Research Letters, 2018 AbstractHarmonically related electromagnetic ion cyclotron waves with the fundamental frequency near the double oxygen cyclotron frequency were observed by the MMS spacecraft on 18–20 May 2016. The wave activity lasted for three days, detected by the spacecraft on their consecutive inbound passages through the Earth's plasma sheet boundary layer.

Magnetic field turbulence, electron heating, magnetic holes, proton cyclotron waves, and the onsets of bipolar pulse (electron hole) events: a possible unifying scenario [PDF]
Nonlinear Processes in Geophysics, 2003 Two electron heating events have been identified on 20 May 1996 when Polar was in the polar cap/polar cusp boundary layer. The electron heating events were located within magnetic holes/cavities/bubbles and were accompanied by nonlinear ± 14 nT peak ...

Dispersion relation of electromagnetic ion cyclotron waves using Cluster observations [PDF]
Annales Geophysicae, 2013 Multi-point wave observations on Cluster spacecraft are used to infer the dispersion relation of electromagnetic ion cyclotron (EMIC) waves. In this study we use a phase differencing method and observations from STAFF and WHISPER during a well-studied

Model of electromagnetic ion cyclotron waves in the inner magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractThe evolution of He+‐mode electromagnetic ion cyclotron (EMIC) waves is studied inside the geostationary orbit using our global model of ring current (RC) ions, electric field, plasmasphere, and EMIC waves. In contrast to the approach previously used by Gamayunov et al.

Propagation of electromagnetic ion cyclotron wave energy in the magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2005 Recent satellite and conjugate observations of Pc 1 electromagnetic ion cyclotron (EMIC) waves have cast doubt on the validity of the long‐standing bouncing wave packet (BWP) model that describes their propagation in the magnetosphere. A study was undertaken using the Combined Release and Radiation Effects Satellite (CRRES) E and B field data to ...
