Understanding cold electron impact on parallel-propagating whistler chorus waves via moment-based quasilinear theory
Opal Issan, Vadim Roytershteyn, Gian Luca Delzanno +1
Earth's magnetosphere hosts a wide range of collisionless particle populations that interact through various wave-particle processes. Among these, cold electrons, with energies bel…

On the origin of the dominant waves in the extended solar corona
Forrest Mozer, Oleksiy Agapitov, Orlando Romeo +2
The extended solar corona at 10-30 solar radii is essentially devoid of all waves below 100 kHz other than triggered ion acoustic waves (TIAW), which consist of a low frequency ele…

Oblique Instability of Quasi-Parallel Whistler Waves in the Presence of Cold and Warm Electron Populations
Vadim Roytershteyn, Gian Luca Delzanno, Justin C. Holmes
Whistler waves propagating nearly parallel to the ambient magnetic field experience a nonlinear instability that generates oblique electrostatic waves, including whistlers near the…
