Enzo: an adaptive mesh refinement code for astrophysics
Greg L. Bryan,Michael L. Norman,Brian W. O'Shea,Tom Abel,John H. Wise,Matthew J. Turk,Daniel R. Reynolds,David C. Collins,Peng Wang,Peng Wang,Samuel W. Skillman,Samuel W. Skillman,Britton D. Smith,Britton D. Smith,Robert P. Harkness,James Bordner,Ji-hoon Kim,Michael Kuhlen,Hao Xu,Nathan J. Goldbaum,Cameron Hummels,Alexei G. Kritsuk,Elizabeth J. Tasker,Stephen Skory,Christine M. Simpson,Oliver Hahn,Jeffrey S. Oishi,Geoffrey C. So,Fen Zhao,Renyue Cen,Yuan Li +30 more
TL;DR: Enzo as discussed by the authors uses block-structured adaptive mesh refinement to provide high spatial and temporal resolution for modeling astrophysical fluid flows, which can be run in one, two, and three dimensions, and supports a wide variety of physics, including hydrodynamics, ideal and non-ideal magnetohydrodynamic, N-body dynamics, primordial gas chemistry, optically thin radiative cooling of primordial and metal-enriched plasmas, and models for star formation and feedback in a cosmological context.

Multi-scale initial conditions for cosmological simulations
Oliver Hahn,Tom Abel,Tom Abel +2 more
TL;DR: In this paper, an adaptive convolution of Gaussian white noise with a real-space transfer function kernel together with an adaptive multi-grid Poisson solver is used to generate displacements and velocities following first- or second-order Lagrangian perturbation theory (2LPT).
Journal ArticleDOI
Properties of dark matter haloes in clusters, filaments, sheets and voids
TL;DR: In this article, the formation histories, shapes and angular momenta of dark-matter halos depend on the environment, and a classification scheme was proposed to distinguish haloes in clusters, filaments, sheets and voids in the large-scale distribution of matter.
Journal ArticleDOI
The evolution of dark matter halo properties in clusters, filaments, sheets and voids
TL;DR: In this paper, a series of high-resolution N-body simulations of the concordance cosmology is used to investigate the redshift evolution since z = 1 of the properties and alignment with the large-scale structure (LSS) of haloes in clusters, filaments, sheets and voids.
