Strongly barred spirals offer a unique laboratory of dynamically distinct environments such as the bar, bar ends, nuclear and inner rings, and spiral arms where the star formation rates and perhaps the cluster dissolution rates vary by orders of magnitude. This proposal aims to add to the shallow existing F658N and F814W HST data to acquire a complete suite of U,B,V, I and Halpha data that will allow us to identify and age-data stellar clusters and measure the cluster mass functions across the various environments. The data will allow us to understand where the stars are forming, how they are evolving and travelling on the different orbital families within the bar, and at what rate they are dissolving into the field population. What makes this study timely is that we have recently been granted high resolution and sensitive observations of the molecular gas and dust in NGC 1097 with ALMA. We also have N-body and purely hydrodynamic simulations of bars that have been used previously to constrain bar dynamics using coarse and low quality data. But now together with the HST and ALMA data plus the models we can confidently measure the triggering mechanisms for star formation, the star formation efficiency, the cluster mass function and dissolution rates in the various environments across this strongly barred system. We seek to map NGC 1097 in multiple filters to achieve our science goals.
