Cosmology and Astrophysics With 21cm Intensity Mapping in the Post-reionization Era

This lecture explores Cosmology and Astrophysics through 21cm intensity mapping in the post-reionization era, presented by Matteo Viel at the International Centre for Theoretical Sciences. Delivered as part of the "Radio Cosmology and Continuum Observations in the SKA Era: A Synergic View" program, the 34-minute talk contributes to discussions about the Square Kilometre Array (SKA) telescope project scheduled to begin operations in 2027. Learn about cutting-edge research in radio cosmology, focusing specifically on how 21cm intensity mapping techniques can reveal insights about the universe after the reionization period. The presentation is part of a comprehensive two-week program bringing together international experts in radio astronomy, with the broader event including both an academic program (April 7-11, 2025) and a training school (April 14-18, 2025) designed for students and early career researchers interested in SKA-related science.
