Event Details

Reionization marks the last major global transition of the Universe, during which the birth of the first luminous cosmic structures gradually reionized the inter-galactic medium. Several observational efforts are devoted to detecting and constraining reionization on small and large scales. In this talk, I will discuss the key questions about the nature of reionization and the various different probes. I will also discuss uncertainties in our current theoretical models and the progress that has been made to answering these questions. In the end, I will present some of my own contributions to improve modeling reionization using a combination of simulations and machine learning methods.
