3D wind-tunnel simulations in the χ~10^3 regime show clump-cocoon geometry sets SB_X/SB_Hα~3, with Hα fraction fixed by atomic physics and X-ray fraction set by residence time in the X-ray band that scales inversely with pressure.

Braginskii-MHD simulations of sloshing cluster cores show that pressure-anisotropy limiters plus turbulent magnetic structure reduce effective viscosity far below the Spitzer value, steepening velocity spectra and dissipating a small fraction of turbulent kinetic energy.
A review summarizing pitfalls in older CR-MHD models and progress toward more rigorous treatments that connect microphysical CR scales to galactic dynamics.

Clumps in a Cocoon: Geometry and Mixing Set the Universal X-ray to H$\alpha$ Surface Brightness Ratio
3D wind-tunnel simulations in the χ~10^3 regime show clump-cocoon geometry sets SB_X/SB_Hα~3, with Hα fraction fixed by atomic physics and X-ray fraction set by residence time in the X-ray band that scales inversely with pressure.

Reduced Effective Viscosity from Anisotropic Transport and Plasma Instabilities in the Sloshing Cores of Galaxy Clusters
Braginskii-MHD simulations of sloshing cluster cores show that pressure-anisotropy limiters plus turbulent magnetic structure reduce effective viscosity far below the Spitzer value, steepening velocity spectra and dissipating a small fraction of turbulent kinetic energy.
