OpenCosmo: Community Portal and Analysis Framework for Flagship Cosmological Simulations
Patrick R. Wells, Michael Buelhmann, Patricia Larsen +11
Cosmology is a precision observational science, and large simulations are necessary components of many analyses. These simulations are computationally expensive and produce massive…
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…
Bayesian "Deep" Process Convolutions: An Application in Cosmology
Kelly R. Moran, Richard Payne, Earl Lawrence +7
The nonlinear matter power spectrum in cosmology describes how matter density fluctuations vary with scale in the universe, providing critical insights into large-scale structure f…
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…
Improving initialization and evolution accuracy of cosmological neutrino simulations
James M. Sullivan, J. D. Emberson, Salman Habib +1
Neutrino mass constraints are a primary focus of current and future large-scale structure (LSS) surveys. Non-linear LSS models rely heavily on cosmological simulations -- the impac…
SPHEREx: NASA's Near-Infrared Spectrophotmetric All-Sky Survey
Brendan P. Crill, Michael Werner, Rachel Akeson +51
SPHEREx, the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and ices Explorer, is a NASA MIDEX mission planned for launch in 2024. SPHEREx will carry ou…
