Abstract

During the next two HST Cycles, the Subaru Strategic Program (SSP) will conduct a rolling search with Hyper Suprime-Cam (HSC) that will discover and study scores of very high quality SNe Ia up to redshift of ~1.5. However, above a redshift of one, the Subaru photometry will be limited to the UV and blue rest-frame of the SNe. By combining the HSC light curve with just one non-disruptive ToO observation and a "reference image" (after the SN has faded) from HST for each of 46 SNe, we will improve the dark energy Figure of Merit (FoM) obtainable from all past and present high-redshift SN searches by a factor of 2.3. This opportunity is unique. Because this search requires frequent changes of the massive HSC at the Subaru prime focus, it will not be repeated for the foreseeable future.
