Understanding the growth rate patterns of ion Bernstein instabilities driven by ring-like proton velocity distributions 

Min, Kyungguk; Liu, Kaijun; 0000-0002-2095-8529; 0000-0001-5882-1328 (2020-06-03)
Fast magnetosonic waves in Earth's inner magnetosphere, which have as their source ion Bernstein instabilities, are driven by hot proton velocity distributions (f(p)) with partial derivative f(p)(v(perpendicular to))/partial ...

VHF and UHF Electromagnetic Radiation Produced by Streamers in Lightning 

Shi, Feng; Dwyer, Joseph R.; Ihaddadene, Kevin M.A.; Liu, Ningyu; (2020-03-10)
In this letter, we report simulation results of streamer propagation and collision that produce electromagnetic radiation in the very high frequency (VHF) and ultra high frequency (UHF) bands. The streamers are initiated ...

Whistler anisotropy instabilities as the source of banded chorus: Van Allen Probes observations and particle-in-cell simulations 

Fu, Xiangrong; Liu, Kaijun; Min, Kyungguk; Winske, Dan; 0000-0001-5882-1328; 0000-0002-2095-8529 (2020-06-05)
Magnetospheric banded chorus is enhanced whistler waves with frequencies (r)<(e), where (e) is the electron cyclotron frequency, and a characteristic spectral gap at (r)similar or equal to(e)/2. This paper uses spacecraft ...
