Scale-dependent alignment in compressible magnetohydrodynamic turbulence
Scale-dependent alignment in compressible magnetohydrodynamic turbulence

Scale-dependent alignment is how turbulence connects to reconnection. We show that the nature of scale-dependent alignment in compressible turbulence differs from well-established incompressible theory.

Comparison of magnetic diffusion and reconnection in ideal and resistive relativistic magnetohydrodynamics, ideal magnetodynamics and resistive force-free electrodynamics
Comparison of magnetic diffusion and reconnection in ideal and resistive relativistic magnetohydrodynamics, ideal magnetodynamics and resistive force-free electrodynamics

Relativistic reconnection is very similar across a broad range of plasma models!

Density Fluctuation–Mach Number Scaling in Compressible, High Plasma Beta Turbulence: In Situ Space Observations and High-Reynolds Number Simulations
Density Fluctuation–Mach Number Scaling in Compressible, High Plasma Beta Turbulence: In Situ Space Observations and High-Reynolds Number Simulations

We compare in situ space observations of Earth's magnetosheath with high resolution data showing that the density fluctuations follow a linear relation with Mach number in both.

So long Kolmogorov: the forward and backward turbulence cascades in a supernovae-driven, multiphase interstellar medium
So long Kolmogorov: the forward and backward turbulence cascades in a supernovae-driven, multiphase interstellar medium

Supernova-driven turbulence is very different from classical Kolmogorov turbulence!

Taking control of compressible modes: bulk viscosity and the turbulent dynamo
Taking control of compressible modes: bulk viscosity and the turbulent dynamo

I've been interested in exploring the nature of different types of viscosity and the role it plays in the dynamo for some time! This is my latest work on trying to marry bulk viscosity -- the type of viscosity generated by out-of-thermal-equilibrium vibrational degrees of freedom (only possible in poly-atomic plasmas) -- and the turbulent dynamo, giving rise to a whole new range of scales -- the sub-bulk-viscous range.

Is The Starry Night Turbulent?
Is The Starry Night Turbulent?

We know that the starry night is turbulent, and that the turbulence is in someway responsible for regulating how the mass density of a star forming cloud gets turned into stars. But did you know that The Starry Night is also turbulent, in that Vincent van Gogh's The Starry Night exhibits some features in k space that are oddly consistent with features of a true turbulent spectrum.
