Formed too fast? The Biggest Galaxies at Cosmic Dawn

The incredible capabilities of the James Webb Space Telescope have allowed us to look back nearly to the very beginning of time, enabling us to observe some of the first galaxies that formed after the Big Bang. Before the launch of JWST, astronomers believed that the first few hundred million years - when the Universe was only a small fraction of its current age - were relatively quiet. To our surprise, we have discovered many more bright galaxies than previously expected. These bright galaxies challenge our understanding of how the first galaxies and black holes formed. In this talk, Dr. Casey will guide us through the journey of discovery in the universe's earliest moments and address some of the key questions raised by JWST’s groundbreaking findings.
