Données manquantes en cosmologie

Resume by AI: This presentation focuses on the challenges and methods in analyzing the 21cm cosmological signal to trace the ionization history of the universe, especially during the epoch of reionization. It discusses the Hydrogen Epoch of Reionization Array (HERA), highlighting data analysis challenges such as radio frequency interference and foreground treatment. Lastly, it explores advanced inference methods like gradient descent and Hamiltonian Monte Carlo to reconstruct density fields and handle missing data.
