Flows For The Masses: A multi-fluid non-linear perturbation theory for massive neutrinos
Joe Zhiyu Chen, Amol Upadhye, Yvonne Y. Y. Wong
Velocity dispersion of the massive neutrinos presents a daunting challenge for non-linear cosmological perturbation theory. We consider the neutrino population as a collection of n…
Hybrid multi-fluid-particle simulations of the cosmic neutrino background
Joe Zhiyu Chen, Markus R. Mosbech, Amol Upadhye +1
Simulation of the cosmic clustering of massive neutrinos is a daunting task, due both to their large velocity dispersion and to their weak clustering power becoming swamped by Pois…
The Mira-Titan Universe IV. High Precision Power Spectrum Emulation
Kelly R. Moran, Katrin Heitmann, Earl Lawrence +6
Modern cosmological surveys are delivering datasets characterized by unprecedented quality and statistical completeness; this trend is expected to continue into the future as new g…
