recommendations! Published in 2018 at "Journal of Geophysical Research"

DOI: 10.1002/2017ja024759

Abstract: The abundant reports on the existence of electromagnetic high-frequency fluctuations in space plasmas have increased the expectations that theoretical modeling may help understand their origins and implications (e.g., kinetic instabilities and dissipation). This paper presents… read more here.
