Illuminating the Physics of Dark Energy with the Discovery Simulations
Gillian D. Beltz-Mohrmann, Adrian Pope, Alex Alarcon +10
In this paper, we present the Discovery simulations: a new pair of high-resolution N-body simulations motivated by the DESI Y1 BAO cosmological constraints on dark energy. The Disc…
The New Worlds Simulations: Large-scale Simulations across Three Cosmologies
Katrin Heitmann, Thomas Uram, Nicholas Frontiere +4
In this paper we describe the set of ``New Worlds Simulations'', three very large cosmology simulations, Qo'noS, Vulcan, and Ferenginar, that were carried out on the Summit superco…
Farpoint: A High-Resolution Cosmology Simulation at the Gigaparsec Scale
Nicholas Frontiere, Katrin Heitmann, Esteban Rangel +7
In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a v…
DESC DC2 Data Release Note
LSST Dark Energy Science Collaboration, Bela Abolfathi, Robert Armstrong +54
In preparation for cosmological analyses of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), the LSST Dark Energy Science Collaboration (LSST DESC) has created…
The Last Journey. I. An Extreme-Scale Simulation on the Mira Supercomputer
Katrin Heitmann, Nicholas Frontiere, Esteban Rangel +10
The Last Journey is a large-volume, gravity-only, cosmological N-body simulation evolving more than 1.24 trillion particles in a periodic box with a side-length of 5.025Gpc. It was…
The Mira-Titan Universe. III. Emulation of the Halo Mass Function
Sebastian Bocquet, Katrin Heitmann, Salman Habib +5
We construct an emulator for the halo mass function over group and cluster mass scales for a range of cosmologies, including the effects of dynamical dark energy and massive neutri…
The Outer Rim Simulation: A Path to Many-Core Supercomputers
Katrin Heitmann, Hal Finkel, Adrian Pope +10
We describe the Outer Rim cosmological simulation, one of the largest high-resolution N-body simulations performed to date, aimed at promoting science to be carried out with large-…
HACC Cosmological Simulations: First Data Release
Katrin Heitmann, Thomas D. Uram, Hal Finkel +10
We describe the first major public data release from cosmological simulations carried out with Argonne's HACC code. This initial release covers a range of datasets from large gravi…
