TL;DR: The Einstein Toolkit as mentioned in this paper is a community-driven, freely accessible computational infrastructure intended for use in numerical relativity, relativistic astrophysics, and other applications, which combines a core set of components needed to simulate astrophysical objects such as black holes, compact objects, and collapsing stars.

TL;DR: In this article, a conformal traceless formulation of the Einstein equations is presented for the study of the gravitational collapse of uniformly rotating neutron stars to Kerr black holes, where the initial stellar models are modeled as relativistic polytropes with angular velocities ranging from slow rotation to the mass shedding limit.

TL;DR: The Einstein Toolkit as discussed by the authors is a community-driven, freely accessible computational infrastructure intended for use in numerical relativity, relativistic astrophysics, and other applications, which combines a core set of components needed to simulate astrophysical objects such as black holes, compact objects, and collapsing stars.

TL;DR: A survey of mature openly available state-of-the-art structured AMR libraries and codes that have been in existence for half a decade or more, have a reasonably sized and active user base outside of their home institutions, and are publicly available.

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.
