Title: Deeper, Wider, Faster: All-wavelength, real-time detection of fast transients and fast radio burst counterparts

Abstract: We propose DECam fast-cadenced imaging to continue our Deeper, Wider, Faster (DWF) program that coordinates major observatories at all- wavelengths to detect and follow-up fast radio bursts (FRBs) and fast transients on millisecond-to-hours timescales. DWF detects FRBs and other elusive fast transients in real time via coordinated simultaneous deep, wide-field, fast-cadenced observations with MeerKAT, Parkes, ASKAP, and/or Molonglo, the South Pole Telescope, CTIO DECam {it (this proposal)}, Astrosat, HXMT, HESS, Pierre Auger, along with other telescopes, to acquire all possible information before the transients fade. These telescopes are on field before, during, and after the fast events and are capable of detecting coherent shorter-wavelength flux arriving to Earth before the FRB detections. DECam is very sensitive to optical bursts for localized/repeater FRBs and capable of detecting and ruling out models. DWF performs real time {it (seconds)} supercomputer data processing and transient identification {it (within minutes of outburst)} of DECam data throughout the night to enable our rapid- response programs on Gemini, VLT, Keck, Swift and others for deep spectroscopy and imaging of the events and their host galaxies, along with conventional ToO and later-time follow up with our programs on SALT, AAT, LCOGT, ATCA, and others. The proposed observations will discover thousands of Galactic and extragalactic fast transients, variable events, and very early detections of slower-evolving transients in this relatively unexplored parameter space. DWF will help characterize the fast transient and variable sky for future large surveys, such as LSST and gravitiational wave searches and offers the best means to resolve the nature of FRBs.
