VHF and UHF Electromagnetic Radiation Produced by Streamers in Lightning 

Shi, Feng; Dwyer, Joseph R.; Ihaddadene, Kevin M.A.; Liu, Ningyu; https://orcid.org/0000-0003-3406-9383 (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 ...
