Sunfall is a production analytics system that accelerates science discovery by utilizing novel interactive visualization and analysis techniques to facilitate insight into complex, noisy, high-dimensional, high-volume, time-critical scientific data. NERSC Analytics staff led a multi-disciplinary team of computer scientists and physicists who designed and implemented Sunfall for the Nearby Supernova Factory, an international astrophysics experiment which is the largest data volume supernova search currently in operation. The Sunfall system combines novel image processing algorithms, statistical analysis, and machine learning with highly interactive visual interfaces to enable collaborative, user-driven scientific exploration of supernova image and spectral data. Now in operation at the Nearby Supernova Factory, Sunfall is the first visual analytics system in production use at a major astrophysics project. Project scientists estimate that Sunfall has reduced the data collection, processing, and management effort from 6 FTE to .75 FTE overall, freeing scientists to focus on science discovery. Additionally, by making previously unworkable scientific tasks possible, Sunfall has enabled scientists to attain new insights into their scientific data.
