TL;DR: The 3D dynamics of magnetorotational core-collapse supernovae are fundamentally different from what was anticipated on the basis of previous simulations in axisymmetry (2D) as discussed by the authors.

TL;DR: In this paper, the authors used the flux-conservative Athena code to conduct a series of experiments on disks having a variety of magnetic topologies to determine what constitutes adequate resolution, and they developed and applied several resolution metrics: (Q{sub z} ) and (q{sub {phi}}), the ratio of the grid zone size to the characteristic MRI wavelength, {alpha}{sub mag}, the relationship between the Maxwell stress to the magnetic pressure, and /, the ratio between radial to toroidal magnetic field energy.

TL;DR: In this paper, the authors use the flux-conservative Athena code to conduct a series of experiments on disks having a variety of magnetic topologies to determine what constitutes adequate resolution, which is characterized by Qz > 15, Qphi > 20, alpha_mag = 0.45, and a field energy ratio of 0.2.

TL;DR: In this article, the effects of the nuclear EOS on GWs from rotating core collapse were examined and the authors carried out 1824 axisymmetric general-relativistic hydrodynamic simulations that cover a parameter space of 98 different rotation profiles and 18 different EOS.

TL;DR: In this article, the authors compare the discrete ordinates (DO) code of Nagakura, Yamada, and Sumiyoshi and the Monte Carlo (MC) code Sedonu, under the assumptions of a static fluid background, flat spacetime, elastic scattering, and full special relativity.
