Explore the statistical properties of the cosmological 21-cm signal in this lecture by Raghunath Ghara from the International Centre for Theoretical Sciences. This 1 hour 20 minute presentation is part of the "Radio Cosmology and Continuum Observations in the SKA Era: A Synergic View" program, which brings together experts in radio cosmology and continuum science to prepare for the Square Kilometre Array (SKA) telescope launching in 2027. The lecture focuses on the analytical and computational methods used to understand the statistical characteristics of 21-cm signals from the early universe, providing valuable insights for researchers interested in cosmological observations. This presentation is particularly relevant for advanced Masters and PhD students, Postdocs, and Early Career Researchers working in radio astronomy and cosmology.
