The Emergence of Galaxies in the First Billion Years - Implications for Reionization, Cosmology and Gravitational Wave Astronomy

Explore a 21-minute conference talk on the emergence of galaxies during the universe's first billion years and its implications for reionization, cosmology, and gravitational wave astronomy. Delivered by Pratika Dayal from the University of Groningen, this presentation was part of the "Cosmic Dawn Revealed by JWST" conference at the Kavli Institute for Theoretical Physics. Delve into key questions about the nature of first stars, black hole seeds, and early galaxy evolution as revealed by JWST observations. Gain insights into the connection between near-field and deep field observations, and understand how these findings challenge and refine theoretical models of galaxy formation. Recorded during a gathering of theorists and observers, this talk contributes to the exciting exploration of cosmic dawn in light of recent JWST discoveries.
