The Last Journey. II. SMACC -- Subhalo Mass-loss Analysis using Core Catalogs
Imran Sultan, Nicholas Frontiere, Salman Habib +4
This paper introduces SMACC -- Subhalo Mass-loss Analysis using Core Catalogs. SMACC adds a mass model to substructure merger trees based on halo "core tracking." Our approach avoi…
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…
CosmoDC2: A Synthetic Sky Catalog for Dark Energy Science with LSST
Danila Korytov, Andrew Hearin, Eve Kovacs +27
This paper introduces cosmoDC2, a large synthetic galaxy catalog designed to support precision dark energy science with the Large Synoptic Survey Telescope (LSST). CosmoDC2 is the…
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…
Dark Energy Survey Year 1 Results: Constraints on Intrinsic Alignments and their Colour Dependence from Galaxy Clustering and Weak Lensing
S. Samuroff, J. Blazek, M. A. Troxel +70
We perform a joint analysis of intrinsic alignments and cosmology using tomographic weak lensing, galaxy clustering and galaxy-galaxy lensing measurements from Year 1 (Y1) of the D…
The Borg Cube Simulation: Cosmological Hydrodynamics with CRK-SPH
J. D. Emberson, Nicholas Frontiere, Salman Habib +4
A challenging requirement posed by next-generation observations is a firm theoretical grasp of the impact of baryons on structure formation. Cosmological hydrodynamic simulations m…
