Excursion-set structure factor of the auroral electric field
Magnus F Ivarsen, Kaili Song, Jean-Pierre St-Maurice +1
We treat coherent radar echoes from aurorae as a finite point process and measure its structure factor from pairwise echo separations. Backscatter requires electron drifts t…

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…
