Star clusters represent a step in the star formation hierarchy above individual stars. As such, they maintain a link to the overall star formation in any galaxy, while their brightness turns them into beacons of star formation in systems out to 100 Mpc. The study of extra-galactic star clusters and their populations has undergone a revival since the launch of HST. However, their use as direct tracers of star formation depends on understanding fundamental laws that regulate the fraction of stars that form in clusters, as well as those that govern the destruction of star clusters.
The Snapshot Hubble U-band Cluster Survey (SHUCS) is designed to take a few steps in that direction. By completing the UBVI baseline for galaxies with existing archival BVI coverage, we will derive the ages, masses and luminosities of thousands of clusters in 22 galaxies. This way we will be able to rule out theories and empirical scenarios regarding the formation and destruction of star clusters, and the role of environment in these processes.
This talk will present a description of the survey and its many goals, and go through some first results.
