Abstract: |
Using deep near-infrared imaging data taken by MOIRCS, we study K-selected objects in the z = 3.1 proto-cluster region in the SSA22a field. The distribution of galaxies at z ∼ 3 is investigated by using the color cut for distant red galaxies (DRGs) and the photometric-redshift selection technique. The marginal density excess of DRGs and the photo-z selected objects is found around the two distinctive luminous Lyα blobs (LABs). We also find that the stellar mass derived for several galaxies in vicinity of each LAB is M* = 109 − 1011M⊙, and the sum of the stellar mass possibly associated with LABs increases with the Lyα luminosity and surface brightness. This result suggests that the origin of Lyα emission appear to be correlated with the previous star formation. |
