The Earth's auroral electrons produce copious non-thermal radio emissions of various types,
including auroral kilometric radiation (AKR), whistler mode auroral hiss, mode conversion …

Sheared flows in near‐Earth space plasmas, both magnetic‐field‐aligned and cross‐field,
contribute to a rich array of phenomena which can be simulated in the laboratory. This has …

Many advances in understanding space plasma phenomena have been linked to insight
derived from theoretical modeling and/or laboratory experiments. Advances for which …

To determine the wavelength of waves within a random, isotropic wave field, we introduce
the observable of wave coherency measured with plasma wave interferometers. We show …

The subject of lower-hybrid solitary structures (LHSS), sometimes called lower-hybrid
cavities, is reviewed. LHSS are spatially localized structures embedded in space plasmas …

In this paper we present a review of sounding rocket observations of the ion acceleration
seen in nightside auroral zone lower hybrid solitary structures. Observations from Topaz3 …

We describe a new class of nonthermal plasma density irregularities observed in the
postmidnight topside equatorial ionosphere under low solar flux conditions. They are distinct …

Rocket observations of spatially localized bursts of intense lower hybrid wave radiation have
been made for decades. As the ability of rocket observations to measure small‐scale …

Measuring plasma wave properties with spatially separated antennae observes wavelength,
propagation speed, and direction as well as frequency. This approach has been pivotal to …

Lower hybrid wave cavities detected by the Freja satellite are analyzed. On the basis of
simple statistical arguments by use of signals from two density probes, it is possible to obtain …
