Abstract

Abstract We present a public data release of halo catalogs from a suite of 125 cosmological N -body simulations from the Abacus project. The simulations span 40 w CDM cosmologies centered on the Planck 2015 cosmology at two mass resolutions, 4 × 10 10 h −1 M ⊙ and 1 × 10 10 h −1 M ⊙ , in 1.1 h −1 Gpc and 720 h −1 Mpc boxes, respectively. The boxes are phase-matched to suppress sample variance and isolate cosmology dependence. Additional volume is available via 16 boxes of fixed cosmology and varied phase; a few boxes of single-parameter excursions from Planck 2015 are also provided. Catalogs spanning z = 1.5 to 0.1 are available for friends-of-friends and Rockstar halo finders and include particle subsamples. All data products are available at https://lgarrison.github.io/AbacusCosmos .
