Abstract
We present preliminary results on the number densities and the clustering properties of three galaxy samples; 2,200 Lyman Break Galaxies (LBGs) at z = 4.0+/-0.5, 300 LBGs at z = 4.7+/-0.5, and 87 Lyman alpha Emitters (LAEs) at z = 4.86. These are found in two deep and wide-survey fields, the Subaru Deep Field (616 arcmin2: z' < 26.0) and the Subaru/XMM Deep Field (653 arcmin2: i' < 26.0). We calculate UV-luminosity functions and angular correlation functions of these three populations. The UV-luminosity functions of LBGs show moderate evolution from z = 4 to z = 5. The angular correlation functions indicate that those galaxies show a stronger clustering than that predicted for underlying dark matter.
