Deeper, Wider, Faster: Using DECam to help chase the fastest bursts in the Universe

Tim Abbott

The Deeper, Wider, Faster (DWF) program coordinates over 50 facilities worldwide and in space, including radio through gamma-ray telescopes, high-energy photon, particle and gravitational wave detectors, to detect and follow up fast transients (millisecond-to-hours duration). Fast transients include fast radio bursts, gravitational waves and their counterparts, supernova shock breakouts, various GRBs, flare stars, and collisions of Type Ia supernovae with companion stars. DWF is the only program of its kind and is a novel use of DECam, as well as a pathfinder for LSST to characterise the fast transient Universe. DWF has three main components: (1) Simultaneous observations for fast transient detections with ~20 facilities (e.g., Parkes, ASKAP, Molonglo, DECam, Swift, and HXMT) for deep, wide-field, fast-cadenced observations of the same field at the same time, (2) Real-time radio, optical and high-energy supercomputer data processing (in seconds) and fast transient identification within minutes of the light hitting the telescopes, via software and human visual inspection using sophisticated visualisation technology, and (3) 1-10m-class rapid-response, conventional ToO, and later-time spectroscopic and imaging follow up of real-time identified events and their host galaxies using ~30 facilities such as Keck, VLT, Gemini, SALT, AAT, Lijiang, Swift, MWA, ATCA, GROND, SkyMapper, CNEOST, and the AST3-2 telescope in the Antarctic.
