摘要：
We report the spectroscopic properties of BzK galaxies in the Subaru Deep Field. We carried out near-infrared spectroscopy of 44 K-AB < 23.4 BzK galaxies with Subaru/MOIRCS, covering wavelengths from 0.9 to 2.3 pin. Among the 44 galaxies, 40 are classified as star-forming galaxies (sBzKs) and four as passive galaxies (pBzKs) based on their B - z vs z - K colors. Half of the 44 are fainter than K-AB = 22. We have detected emission lines such as Ha in 15 sBzKs, of which nine are K-AB > 22. Here we report the redshift distribution and specific star formation rate for the sBzKs with a spectroscopic redshift.
