Optimal data compression for Lyman- forest cosmology
Francesca Gerardi, Andrei Cuceu, Benjamin Joachimi +2
The Lyman- (Ly) three-dimensional correlation functions have been widely used to perform cosmological inference using the baryon acoustic oscillation (BAO) scale. While the t…

Unbiased likelihood-free inference of the Hubble constant from light standard sirens
Francesca Gerardi, Stephen M. Feeney, Justin Alsing
Multi-messenger observations of binary neutron star mergers offer a promising path towards resolution of the Hubble constant () tension, provided their constraints are shown t…

Reconstruction of the Dark Energy equation of state from latest data: the impact of theoretical priors
Francesca Gerardi, Matteo Martinelli, Alessandra Silvestri
We reconstruct the Equation of State of Dark Energy (EoS) from current data using a non-parametric approach where, rather than assuming a specific time evolution of this function,…
