Abstract

In order to search for high-redshift galaxies around z 6 in the Subaru Deep Field, we have investigated NB816-dropout galaxies where NB816 is the narrowband filter centered at 815nm with FWHM of 12.5 nm for the Suprime-Cam on the Subaru Telescope. Since the NB816 imaging is so deep we can detect 10 well-defined NB816-dropout galaxies that we identify to lie at z = 5.8 -- 6.5. We discuss their observational properties.
