Description
How Much Do We Understand About Early Galaxy Formation?
The “Cosmic Dawn” of galaxy formation is one of the frontiers of modern astronomy. In the past two years, JWST has provided tantalizing clues about sources in the first several hundred million years of the Universe’s history that challenge our understanding this era, including an apparent overabundance of bright galaxies during the early phases, evidence for strong fluctuations in the star formation rate of sources, and a surprising abundance of accreting supermassive black holes. I will use a simple galaxy formation framework to describe how we can leverage these new observations to learn how early galaxy formation may differ from our expectations and how we hope to study the very first star clusters to form in the Universe.
