Emulator-Based Inference of Cosmological Subgrid Models
Nesar Ramachandra, Nicholas Frontiere, Michael Buehlmann +4
The formation of structure in the Universe at large scales is dominated by gravity, with baryonic physics becoming significant at scales. To capture the impact of b…
Modeling Galaxy Formation in Cosmological Simulations with CRK-HACC
Nicholas Frontiere, J. D. Emberson, Michael Buehlmann +4
Self-consistently modeling baryonic effects in survey-scale cosmological simulations has become increasingly important as the diversity, precision, and statistical reach of modern…
A Gigaparsec-Scale Hydrodynamic Volume Reconstructed with Deep Learning
Cooper Jacobus, Roger de Belsunce, Solene Chabanier +4
The next generation of cosmological spectroscopic sky surveys will probe the distribution of matter across several Gigaparsecs (Gpc) or many billion light-years. In order to levera…
Cosmological Hydrodynamics at Exascale: A Trillion-Particle Leap in Capability
Nicholas Frontiere, J. D. Emberson, Michael Buehlmann +10
Resolving the most fundamental questions in cosmology requires simulations that match the scale, fidelity, and physical complexity demanded by next-generation sky surveys. To achie…
The picasso gas model: Painting intracluster gas on gravity-only simulations
F. Kéruzoré, L. E. Bleem, N. Frontiere +5
We introduce picasso, a model designed to predict thermodynamic properties of the intracluster medium based on the properties of halos in gravity-only simulations. The predictions…
