Published in 2020 at "Journal of Atmospheric and Solar-Terrestrial Physics"

DOI: 10.1016/j.jastp.2020.105292

Abstract: Abstract Although the occurrence rate of electromagnetic ion cyclotron (EMIC) waves is high in the outer magnetosphere (L > 7), it has been suggested in the past that a steep plasma density gradient region of the plasmapause… read more here.

Published in 2019 at "Geophysical Research Letters"

DOI: 10.1029/2019gl083456

Abstract: In this paper, we find that hot He+ ions significantly alter the kinetic dispersion relation of electromagnetic ion cyclotron (EMIC) waves and thus strongly affect the wave‐driven electron pitch angle scattering rates. Increasing hot He+… read more here.

Published in 2021 at "Geophysical Research Letters"

DOI: 10.1029/2020gl090921

Abstract: Wave growth of electromagnetic ion cyclotron (EMIC) emissions observed in the outer magnetosphere is mainly controlled by compression events resulting from solar wind dynamic pressure pulses. During such events wave growth is expected to be… read more here.

Published in 2021 at "Journal of Geophysical Research"

DOI: 10.1029/2020ja028878

Abstract: The spatial and temporal distributions of ionospheric electromagnetic ion cyclotron (EMIC) waves during magnetic storms from 2014 to 2018 were studied using Swarm observations. Ionospheric EMIC waves preferably occurred during storms and their recovery phases… read more here.

Published in 2022 at "Geophysical Research Letters"

DOI: 10.1029/2021gl097620

Abstract: Fast‐localized electron loss, resulting from interactions with electromagnetic ion cyclotron (EMIC) waves, can produce deepening minima in phase space density (PSD) radial profiles. Here, we perform a statistical analysis of local PSD minima to quantify… read more here.

Published in 2022 at "Geophysical Research Letters"

DOI: 10.1029/2022gl098365

Abstract: Recent work has shown that ElectroMagnetic Ion Cyclotron (EMIC) waves tend to occur in four distinct regions, each having their own characteristics and morphology. Here, we use nonlinear test‐particle simulations to examine the range of… read more here.
