We propose deep, fast-cadenced Hyper Suprime-Cam observations as part of our successful Deeper, Wider, Faster (DWF) program to detect and study fast transients, including fast radio bursts (FRBs), in the relatively unexplored seconds-to-hours time domain. DWF coordinates ∼25 committed radio, optical, infrared, and high-energy observatories as part of our program. We will detect and study FRBs and fast transients in real time (1) by obtaining simultaneous deep, multi-wavelength, fast-cadenced observations using Parkes, Molonglo, HSC and Swift (+ others), (2) by performing real-time supercomputer data processing and candidate identification in seconds to minutes, (3) by acquiring rapid-response (in minutes) spectroscopy and imaging of events and their host galaxies using Gemini, Swift, the AAT (+ others), and (4) by utilising our a network of 1–10m telescopes for conventional ToO and long-term follow-up observations. The proposed HSC observations are the anchor to this program and will provide the necessary wide-field and depth to probe large volumes and discover hundreds of Galactic and extra-galactic fast transients out to high redshift. Along with the DWF facilities, the HSC observations have the capability to resolve the overall nature of FRBs in one shot.
