Over recent decades, cosmological simulations of galaxy formation have been instrumental
in advancing our understanding of structure and galaxy formation in the Universe. These …

We review the field of collisionless numerical simulations for the large-scale structure of the
Universe. We start by providing the main set of equations solved by these simulations and …

We present the public data release of the AbacusSummit cosmological N-body simulation
suite, produced with the Abacus N-body code on the Summit supercomputer of the Oak …

Numerical methods have become a powerful tool for research in astrophysics, but their utility
depends critically on the availability of suitable simulation codes. This calls for continuous …

We measure the clustering of quasars of the final data release (DR16) of eBOSS. The
sample contains quasars between redshifts 0.8≤ z≤ 2.2 over. We calculate the Legendre …

We introduce the Astrid simulation, a large-scale cosmological hydrodynamic simulation in a
box with 2× 55003 particles. Astrid contains a large number of high redshift galaxies, which …

The relation between halo mass, M, and concentration, c, is a critical component in our
understanding of the structure of dark matter halos. While numerous models for this relation …

We describe the observations and resultant galaxy cluster catalog from the 2770 deg 2
SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev …

We report on the successful completion of a 2 trillion particle cosmological simulation to z= 0
z=0 run on the Piz Daint supercomputer (CSCS, Switzerland), using 4000+ GPU nodes for a …

Today's computational, experimental, and observational sciences rely on computations that
involve many related tasks. The success of a scientific mission often hinges on the computer …
