Reconnection-controlled decay of magnetohydrodynamic turbulence and the role of invariants
David N. Hosking, Alexander A. Schekochihin
We present a new theoretical picture of magnetically dominated, decaying turbulence in the absence of a mean magnetic field. We demonstrate that such turbulence is governed by the…

A First-Principle Model for Polarization Swings during Reconnection-Powered Flares
David N. Hosking, Lorenzo Sironi
We show that magnetic reconnection in a magnetically-dominated fast-cooling plasma can naturally produce bright flares accompanied by rotations in the synchrotron polarization vect…

Elasticity of tangled magnetic fields
D. N. Hosking, A. A. Schekochihin, S. A. Balbus
The fundamental difference between incompressible ideal magnetohydrodynamics and the dynamics of a non-conducting fluid is that magnetic fields exert a tension force that opposes t…
