Title: The Keck Wide-Field Imager
Abstract:
The Keck Wide-Field Imager (KWFI) is a 1-degree diameter field of view UV-sensitive optical camera for the Keck telescopes. KWFI will be the most sensitive wide-field camera in the world and the only such 8m-class camera sensitive from 10000A down to 3000A for the foreseeable future. Reaching magnitudes of m ~ 28 – 30 (~25 – 4 nano-Jy) depths over wide fields, including the u-band, KWFI plays an essential role for upcoming 30m-class telescopes, wide-field space missions and JWST, future gravitational wave detectors, and wide-field 8m-class multi-object spectroscopic instruments. In this talk, I will discuss the future landscape for wide-field imagers, the KWFI instrument, its status, and the path forward. KWFI will progress science in nearly every area of astronomy, from high to low redshift and time-domain science. Moreover, the unique capabilities of KWFI will enable world-leading science that cannot be done on any other telescope, not even 30m-class telescopes. For example, KWFI is the only imager that can detect, map, and characterise high redshift galaxy population emitting ionising Lyman continuum flux to better understand cosmic reionisation; the only imager with the sensitivity and rapid response capability to localise and discover the bulk of the kilonovae detected by current and future gravitational wave detectors; and the only imager to provide wide-field 3000-5000A photometry down to m ~ 29 necessary for Roman and Euclid deep fields.
