The Subaru Seminar is usually held in Room 104 of the Hilo Base Facility, adjacent to the main lobby. Everyone is welcome to attend. If you are interested in giving a seminar, please contact Subaru seminar organizers (Tadayuki Kodama, Kumiko S. Usuda, Naoyuki Tamura, Tomonori Usuda) by email : sseminar_at_subaru.naoj.org (please change"_at" to @).

" What is your WISH? "

Ikuru Iwata

(Subaru Telescope)


I would like to introduce WISH, the Wide-field Imaging Surveyor for High-redshift. It is a space science mission whose primary goal is to reveal the first-generation galaxies in the early universe. We will launch a 1.5m-aperture telescope equipped with very wide-field (~800 square arcminutes, comparable to the current Subaru prime-focus camera) near-infrared camera, which covers 1 to 5 microns. The ultra-deep survey of WISH will reach 28 AB magnitude, which cannot be achieved by any ground-base telescopes, and plans to cover 100 square degrees of the extragalactic sky. This WISH UDS should detect enormous amount of galaxies in the dawn of the universe, and such galaxies are sufficiently bright to be followed-up spectroscopically with the extremely large telescopes such as TMT. In this sense, WISH is quite complimentary to JWST, and the WISH and TMT are an ideal combination to understand how the first generation of galaxies are formed. Also, the depth, survey area and wavelength coverage of WISH should be quite valuable to other astronomical and cosmological research fields, such as dark energy, evolution of galaxies and AGNs, mapping our Galaxy and the solar system. In this talk, I will summarize the technological development made for WISH so far, and characterize its uniqueness compared to other space-telescope projects under consideration, such as Euclid and WFIRST.


Seminars are also held at JAC, CFHT, and IfA.
