Learning About Cosmic Dawn with the 21-cm Signal

This lecture explores the fascinating topic of Cosmic Dawn through the lens of the 21-cm signal, presented by Anastasia Fialkov at the International Centre for Theoretical Sciences. Discover how the 21-cm hydrogen line serves as a crucial tool for understanding the early universe during the "Radio Cosmology and Continuum Observations in the SKA Era" program. The 28-minute presentation delves into how the upcoming Square Kilometre Array (SKA) telescope will revolutionize our understanding of cosmic dawn when it begins operations in 2027. Gain insights into the cutting-edge research methods being developed to detect and analyze these faint signals from the universe's earliest epochs. This talk is part of a comprehensive two-week program bringing together international experts in radio cosmology and continuum science, designed to foster collaboration and train the next generation of researchers in preparation for the SKA era.
