Dark Energy from Planck to Euclid: degeneracies in the dark sector

Valeria PETTORINO (CosmoStat, CEA Paris-Saclay) interviendra le vendredi 06 mars 2020 à 11h dans l'Amphi Pierre-Gilles de Gennes (Condorcet) dans le cadre du colloque "Dark Energy from Planck to Euclid: degeneracies in the dark sector".

Abstract :  She will give a general overview on Dark Energy in cosmology, state of the art after Planck and open challenges in view of residual tensions and next to come surveys.
She will then discuss different ways we can us to break degeneracies among cosmological models and how weak lensing peaks counts and machine learning can help for this purpose.
