TL;DR: In this paper, a frequency-domain matching of post-Newtonian inspiral waveforms with numerical relativity based binary black hole coalescence waveforms is proposed to quantify the various possible sources of systematic errors that arise in matching post-newtonian and numerical relativity waveforms, and use a matching criteria based on minimizing these errors.

TL;DR: It is shown that hydromagnetic turbulence in rapidly rotating protoneutron stars produces an inverse cascade of energy, and a large-scale, ordered toroidal field is found that is consistent with the formation of bipolar magnetorotationally driven outflows.

TL;DR: In this article, the authors studied the 3D hydrodynamics of the post-core-bounce phase of the collapse of a 27 M_☉ star and paid special attention to the development of the standing accretion shock instability (SASI) and neutrino-driven convection.

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 present the new general-relativistic magnetohydrodynamics (GRMHD) capabilities of the Einstein toolkit, an open-source community-driven numerical relativity and computational relativistic astrophysics code.
