Resolved Mapping of Star Formation in Ultra-Faint Reionzation-Era Galaxies — Following the JWST ERS and Cycle 2 GO Announcement of Opportunity published on July 6, 2023, the CSA is providing funding via a Grant Agreement to the university to conduct their research using the JWST data. 

It has long been postulated that massive young stars in small dwarf galaxies are the source of photons that drive reionization. This project will employ a new method of detecting dwarf galaxies using medium bands. Once these galaxies are found they will be fully mapped in 2D.  This will uncover what is causing the intense star-formation within them, and how the energetic photons that reionize the Universe escape from these galaxies.
