Research Abstract

We perform very deep imaging over 2 square degree blank fields with Subaru/Suprime-Cam. Combining the optical data with publicly available near-infrared imaging data, we detect in total 6 candidates of star-forming galaxies at redshift 7. It is shown that the resultant UV luminosity function of galaxies are well fitted by either of the conventional Schechter function or a double-power law function, with no significant evolution in the bright end during 0. 3 Giga-years of this cosmic era, with the aid of the newly added bright-end sample.
