Cosmic Dawn Revealed by JWST: The Physics of the First Stars, Galaxies, and Black Holes

Coordinators: Volker Bromm, Roberto Maiolino, Brant Robertson, Rachel Somerville, and Marta Volonteri

The exploration of cosmic dawn is currently in an exceptionally exciting phase, and we expect the immediate future to be even more exciting with a new set of discoveries delivered by JWST. The observations of first stars, galaxies, and black holes with JWST and other facilities provide a unique “stress test” for a new generation of theoretical models of galaxy formation. The aim of the conference is to bring together theorists and observers to discuss the following key questions: What can we learn from JWST data on the nature of the first stars and black hole seeds? What is the nature of the stellar populations inhabiting the first galaxies? What are the star formation and chemical enrichment histories of early galaxies? Do we understand the key physical processes that shape the evolution of these early galaxies and their black holes? How can we connect the pictures derived from near-field and deep field observations?

Use this form to apply for a lightning talk at the Cosmic Dawn Revealed by JWST: the Physics of the First Stars, Galaxies and Black Holes conference. We anticipate that lightning talks will be approximately 5 minutes in length. Please note that a limited number of talk slots are available. To receive first consideration, this form must be submitted by 11:59pm eastern time on June 21. Submitting a lighting talk does not register you for the conference and only those who are registered for the conference will be considered for a lightning talk.
