A unique feature of whistler chorus wave observations is the power gap at frequencies near half the electron gyrofrequency, which is observed approximately 2/3 of the time. 1 Additionally, some of these observations have multiple power gaps, which ar

The unprecedented high-resolution data from the Magnetospheric Multi-Scale (MMS) satellites is revealing the physics of dipolarization fronts created in the aftermath of magnetic reconnection in extraordinary detail. The data shows that the fronts co

We develop a Bayesian spectral analysis technique that calculates the probability distribution functions of a superposition of wave modes each described by a linear growth rate, a frequency, and a chirp rate. The Bayesian framework has a number of ad

Dipolarization fronts (DFs) are fast Earthward propagating plasma structures with spatial gradients (in the frame moving with the front) of the order of the ion gyroradius or smaller. Broadband, mostly electrostatic, wavepower is observed at the fron

The SMART (Space Measurement of A Rocket-released Turbulence) experiment will demonstrate the production of electromagnetic waves in the space environment via a cascade of plasma physics processes. A sounding rocket will release heavy atoms into the

Plasma impedance probes are often used in laboratory experiments as well as in space to make measurements of important plasma parameters such as the electron density. Conventional impedance probe methods involve sweeping the frequency applied to the

Impedance probe measurements are made at ionospheric (F-region) plasma conditions ( $n_{e}\approx 10^{4}$ – $10^{6}$ cm $^{-3}$ and $\lambda _{D}\approx 1$ –10 cm) created in the Space Physics Simulation Chamber at the Naval Research Laboratory.
