Title: UV Light Reveals the Life of Giant Star-forming Clumps
Cycle: 27

Understanding the formation of the Hubble Sequence requires detailed studies of galaxy structures over cosmic time. A prominent structural feature of distant star-forming galaxies is giant star-forming clumps. The origin and evolution of these clumps and their role in galaxy formation are still under debate. An important open question is whether clumps are long lived and migrating towards the galactic center to form bulges or if they are quickly disrupted by feedback. The keys to solve this puzzle are (1) accurate measurements of clump properties and (2) direct comparisons with models and simulations, neither of which has been sufficiently accomplished. We propose to study clumps at 0.5
