One line to run them all: SuperEasy massive neutrino linear response in -body simulations
Joe Zhiyu Chen, Amol Upadhye, Yvonne Y. Y. Wong
We present in this work a novel and yet extremely simple method for incorporating the effects of massive neutrinos in cosmological -body simulations. This so-called "SuperEasy l…
The cosmic neutrino background as a collection of fluids in large-scale structure simulations
Joe Zhiyu Chen, Amol Upadhye, Yvonne Y. Y. Wong
A significant challenge for modelling the massive neutrino as a hot dark matter is its large velocity dispersion. In this work, we investigate and implement a multi-fluid perturbat…
Invisible neutrino decay in precision cosmology
Gabriela Barenboim, Joe Zhiyu Chen, Steen Hannestad +3
We revisit the topic of invisible neutrino decay in the precision cosmological context, via a first-principles approach to understanding the cosmic microwave background and large-s…
