How and when did the cosmic dark ages end? I will present the remarkable story of how the first stars and galaxies formed, a few hundred million years after the Big Bang. These first sources of light fundamentally transformed the early universe from an initially very simple state to one of ever increasing complexity. Until now, our knowledge of this period of cosmic dawn relies on supercomputer simulations. But over the next decade, a number of new-generation observational facilities, such as the James Webb Space Telescope and the Giant Magellan Telescope, will test our understanding. Completing our century-old quest, we will finally be able to open up a direct window into the very beginning of cosmic star and galaxy formation.
These talks are held in partnership with the Cleveland Museum of Natural History at 8:00pm on Thursday nights. Admission is free to the general public; parking is available in the museum lot for a $6 charge.
