Extreme, transient bursts of energy in the auroral ionosphere. II. A magnetotail dipolarization event
Magnus F Ivarsen, Yukinaga Miyashita, Brian Pitzel +5
We report ground-based coherent VHF radar observations of extreme turbulent field-structures detected in coincidence with a magnetospheric substorm-associated magnetotail dipolariz…

Kinetic renormalization of auroral turbulence
Magnus F Ivarsen, Kaili Song, Luca Spogli +19
Driven-dissipative systems often exhibit self-organization in the form of coherent dissipative structures. However, observing such critical states in natural plasmas remains elusiv…

A Characteristic Signature of Magnetospheric Wave-Particle Interactions Found in the Turbulent E-region
Magnus F Ivarsen, Yukinaga Miyashita, Jean-Pierre St-Maurice +16
Plasma waves in the magnetosphere scatter electrons, causing them to precipitate into Earth's atmosphere, imparting their temporal characteristics to diffuse auroras. In a case stu…
