The DESI Experiment Part I: Science,Targeting, and Survey Design

Amir Aghamousa, +291 more
TL;DR: DESI as discussed by the authors is a ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through redshift-space distortions with a wide-area galaxy and quasar redshift survey.

The coyote universe extended: precision emulation of the matter power spectrum

TL;DR: In this article, the authors present a large-scale, multi-physics simulation capability covering a range of cosmological models and astrophysical processes for the matter power spectrum.
Journal ArticleDOI

The Coyote Universe II: Cosmological Models and Precision Emulation of the Nonlinear Matter Power Spectrum

TL;DR: In this paper, a limited set of only 37 cosmological models (the "Coyote Universe" suite) is used to predict the nonlinear matter power spectrum at the required accuracy over a prior parameter range set by cosmic microwave background observations.
Journal ArticleDOI

Dark Matter Halo Profiles of Massive Clusters: Theory vs. Observations

TL;DR: In this article, a gravity-only simulation of the concordance LCDM cosmology is carried out, covering a mass range of 210 −12 −15 −15 solar mass and a redshift range of z = 0 −2, while satisfying the associated requirements of resolution and statistical control.
