Abstract

ULTIMATE-Subaru is a next large facility instrument program at Subaru telescope, which will develop 14 x14 arcmin2 wide-field near-infrared imager and multi-object spectrograph with the aid of ground-layer adaptive optics system (GLAO) at the Cassegrain and Nasmyth foci of the telescope in mid 2020s. Our preliminary performance simulation indicates that the GLAO system at Subaru telescope can provide uniform seeing improvement down to FWHM~0.2 arcsec in K band under moderate seeing condition across the field of view up to 20 arcmin in diameter. The main science case of the ULTIMATE-Subaru is a complete census of galaxy evolution from cosmic dawn (z>8) to cosmic noon (z=1-3) with ultradeep, wide-field narrow-band imaging and multi-object spectroscopies of a statistical sample of galaxies especially in K band.
