  journal={The Astrophysical Journal Supplement Series},
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 volume of (1000h −1 Mpc)3 and evolves close to two trillion particles, corresponding to a mass resolution of m p ∼ 4.6 × 107 h −1 M ⊙. These specifications enable comprehensive investigations of the galaxy–halo connection, capturing halos down to small masses. Further, the large volume resolves scales typical of modern… 


The Q Continuum Simulation: Harnessing the Power of GPU Accelerated Supercomputers
Modeling large-scale sky survey observations is a key driver for the continuing development of high resolution, large-volume, cosmological simulations. We report the first results from the 'Q
The Outer Rim Simulation: A Path to Many-core Supercomputers
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-scale structure
Resolving cosmic structure formation with the Millennium-II simulation
We present the Millennium-II Simulation (MS-II), a very large N-body simulation of dark matter evolution in the concordance A cold dark matter (ACDM) cosmology. The MS-II assumes the same
Scaling relations for galaxy clusters in the Millennium-XXL simulation
We present a very large high-resolution cosmological N-body simulation, the Millennium-XXL or MXXL, which uses 303 billion particles to represent the formation of dark matter structures throughout a
PKDGRAV3: beyond trillion particle cosmological simulations for the next era of galaxy surveys
The very low memory footprint of PKDGRAV3 allowed us to run the first ever benchmark with 8 trillion particles on Titan, and to achieve perfect scaling up to 18,000 nodes and a peak performance of 10 Pflops.

The MICE Grand Challenge lightcone simulation – II. Halo and galaxy catalogues
This is the second in a series of three papers in which we present an end-to-end simulation from the MICE collaboration, the MICE Grand Challenge (MICE-GC) run. The N-body contains about 70 billion
A Differentiable Model of the Assembly of Individual and Populations of Dark Matter Halos
We present a new empirical model for the mass assembly of dark matter halos.We approximate the growth of individual halos as a simple power-law function of time, where the power-law index smoothly

This paper introduces Colossus, a public, open-source python package for calculations related to cosmology, the large-scale structure (LSS) of matter in the universe, and the properties of dark
Halo Profiles and the Concentration–Mass Relation for a ΛCDM Universe
Profiles of dark matter-dominated halos at the group and cluster scales play an important role in modern cosmology. Using results from two very large cosmological $N$-body simulations, which increase
