| Summary:
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 supercomputer with the Hardware/Hybrid Cosmology Code, HACC.
The gravity-only simulations follow the evolution of structure in the Universe
by each employing 12,288^3 particles in (3 Gpc/h)^3 volumes, leading to a mass
resolution of m_p~10^9 Msun/h. The simulations cover three different
cosmologies, one LambdaCDM model, consistent with measurements from Planck, one
simulation with massive neutrinos, and one simulation with a varying dark
energy equation of state. All simulations have the same phases to allow a
detailed comparison of the results and the investigation of the impact of
different cosmological parameters. We present measurements of some basic
statistics, such as matter power spectra, correlation function, halo mass
function and concentration-mass relation and investigate the differences due to
the varying cosmologies. Given the large volume and high resolution, these
simulations provide excellent bases for creating synthetic skies. A subset of
the data is made publicly available as part of this paper.
