Tomo-e Gozen is an optical survey project with a wide-field mosaic CMOS camera
on the 1.0-m Schmidt telescope at Kiso Observatory, the University of Tokyo. The
Tomo-e Gozen camera is capable to obtain consecutive frames of 20 square degree
sky with 2 fps (max) by using 84 chips of 1k x 2k CMOS imaging sensors. High-cadence
northern sky survey with 40,000 square degrees will start from Apr. 2019 to detect
transient phenomena of supernovae, AGNs, stellar flares, black hole binaries, pulsars,
magnetars, exoplanets, trans-Neptunian objects, asteroid bursts, near earth objects,
and meteors. When getting alerts of gravitational wave and neutrino detections, the
Tomo-e Gozen camera will follow-up sky areas in their localization maps. The survey
observations produce movie data of 20 TBytes/night. Transient phenomena
are mined from the big-data by an on-the-fly processing software with AI
technologies on a computing system with 200 CPUs and 900 TBytes storage at Kiso
Observatory to issue alerts for further follow-ups by other telescopes. |
