A representation learning approach to probe for dynamical dark energy in matter power spectra
Davide Piras, Lucas Lombriser
We present DE-VAE, a variational autoencoder (VAE) architecture to search for a compressed representation of dynamical dark energy (DE) models in observational studies of the cosmi…

CosmoPower-JAX: high-dimensional Bayesian inference with differentiable cosmological emulators
D. Piras, A. Spurio Mancini
We present CosmoPower-JAX, a JAX-based implementation of the CosmoPower framework, which accelerates cosmological inference by building neural emulators of cosmological power spect…
