"How were the most ancient objects in the universe formed? "

Abstract:

Ancient remnants from the early universe surround our galaxy, which you may know as globular clusters. Although now on their old age, understanding how these clusters were formed has the potential to provide insight into the physical conditions that prevailed during an epoch that cannot be directly observed. We now know that globular clusters can form during extreme episodes of star formation in the relatively nearby universe, but the actual physical conditions that give rise to globular clusters have vexed both observers and theorists for decades. With the new capabilities of JWST along with the Atacama Large Millimeter/submillimeter Array (ALMA) we are uncovering new clues about the environments in which these extreme clusters form. This talk will give an overview of progress that has been made in understanding globular clusters, and highlight the importance of using chemistry to understand physical conditions in space.
