Subaru Surveys for High-z Galaxies

Abstract

We present a summary of optical/NIR deep surveys for very high-$z$ galaxies using the 8.2m Subaru Telescope operated by National Astronomical Observatory of Japan. The prime focus mosaic CCD camera, Suprime-Cam, with a very wide field of view, 34${}^{\prime }\times 27^{\prime }$, allows us to carry out efficient optical deep surveys. In particular, the Subaru Deep Field project has provided us a number of Lyman$\alpha$ emitters beyond $z=6$. We discuss the star formation history in the early universe based on this project.
