| Abstract: |
We present the results of a near-infrared multi-object spectroscopic (MOS) observation of sBzK color and Spitzer/MIPS 24μm selected galaxies, which are used to examine the rest-optical spectroscopic properties of infrared luminous galaxies at z ∼ 2. Both dust-corrected Hα luminosity and MIPS flux show consistent star formation rate, but some galaxies have moderate excess of MIPS flux. Star-formation time scales from Hα star formation rates and the stellar mass of our sample shows that massive ultra-luminous red galaxies (ULIRGs) are forming most of their stars during the redshift range of our sample. |
