Resistive GRMHD simulations of rotating neutron stars show resistivity changes magnetic field geometries, suppresses instabilities, and lowers GW emission amplitude while maintaining a consistent 9:1 poloidal-to-toroidal energy ratio over 100 ms.

abstract
The analysis of complex multiphysics astrophysical simulations presents a unique and rapidly growing set of challenges: reproducibility, parallelization, and vast increases in data size and complexity chief among them. In order to meet these challenges, and in order to open up new avenues for collaboration between users of multiple simulation platforms, we present yt (available at http://yt.enzotools.org/), an open source, community-developed astrophysical analysis and visualization toolkit. Analysis and visualization with yt are oriented around physically relevant quantities rather than quantities native to astrophysical simulation codes. While originally designed for handling Enzo's structure adaptive mesh refinement (AMR) data, yt has been extended to work with several different simulation methods and simulation codes including Orion, RAMSES, and FLASH. We report on its methods for reading, handling, and visualizing data, including projections, multivariate volume rendering, multi-dimensional histograms, halo finding, light cone generation and topologically-connected isocontour identification. Furthermore, we discuss the underlying algorithms yt uses for processing and visualizing data, and its mechanisms for parallelization of analysis tasks.

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.
Shell-to-shell transfer analysis in decaying MHD turbulence demonstrates direct non-local inverse energy transfer from the integral scale, resulting in multiplicative growth of large-scale magnetic energy, confined within helical sectors when net helicity is zero.
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.
Inelastic neutrino-electron scattering in hypermassive neutron star simulations increases disc mass by 75% and ejecta mass by 18% with higher neutrino luminosities, while electron-positron annihilation shows no significant impact.

Inverse energy transfer in decaying MHD turbulence: A shell-to-shell analysis
Shell-to-shell transfer analysis in decaying MHD turbulence demonstrates direct non-local inverse energy transfer from the integral scale, resulting in multiplicative growth of large-scale magnetic energy, confined within helical sectors when net helicity is zero.
