As a part of Mahalo-Subaru project, we performed a deep narrow-band imaging with Subaru/MOIRCS in the SXDF-CANDELS field. We construct samples of [OIII] emission line galaxies at z=3.2 and 3.6, and investigate their global physical properties, such as stellar mass and star formation rate (SFR). The stellar mass and SFR of the [OIII] emitters show clear correlation known as the ’main sequence’ of star-forming galaxies. Comparing with the Hα emitters at z~2, we find that the location of the sequence of the [OIII] emitters is almost identical to that of the Hα emitters. However, the distribution of galaxies along the sequence is systematically different between the two samples. In this talk, I will show our results about NB-selected [OIII] emitters at z > 3, and discuss what is suggested from the different distribution of galaxies on the main sequence diagram between the two different epochs. |
