Implicit Likelihood Inference and $z$ -Binned Reconstruction of Dark Energy $w (z)$

Ke Wang, Jia-Yi Feng, Jianbo Lu

In this paper, to reconstruct the equation of state (EOS) of dark energy (DE) $w (z)$ with the redshift binning method, we first introduce a $w_{i}$ CDM model with a piecewise-constant…

Implicit Likelihood Inference of the Neutrino Mass Hierarchy from Cosmological Data

Ke Wang, Jia-Yi Feng

In this paper, we turn to the Learning the Universe Implicit Likelihood Inference (LtU-ILI) pipeline to perform a multi-round ILI of the neutrino mass hierarchy from cosmological d…
