Title: WISH: Wide-field Imaging Surveyor for High-redshift
Date (JST): Thu, Nov 21, 2013, 14:00 - 15:00
Place: Seminar Room A
Abstract: WISH is a concept being developed and will be proposed for Japanese JAXA/ISAS future space science mission whose primary goal is to study the first-generation of the galaxies beyond the epoch of Cosmic Reionization at z=8-15 as well as to conduct extensive search and light curve monitoring of high redshift type-Ia SNe at z=0-2 to study the accurate history of the cosmic expansion and Dark Energy. WISH has a telescope with the primary mirror with 1.5m diameter and the wide-field NIR camera with the field of view of 850 arcmin^2, and is dedicated for very deep and wide-area sky survey at the wavelength of 1-5 micron (NIR). The key survey is in 5-6 broad band filters with 28AB and 100 deg^2, which is combined with relatively shallow wider survey as well as with the extremely deep drilling survey. WISH should be a very powerful and unique facility in many other fields in astronomy as well. In this talk, I will introduce the current status, science cases, international collaboration, and future prospects of the WISH project.
