dc.description.abstractWe present an analysis of physical properties of 34 [O III] emission-line galaxies (ELGs) at z = 3.254 ± 0.029 in the Extended Chandra Deep Field South (ECDFS). These ELGs are selected from deep narrow H2S(1) and broad Ks imaging of 383 arcmin2 obtained with CFHT/WIRCam. We construct spectral energy distributions (SEDs) from U to Ks to derive the physical properties of ELGs. These [O III] ELGs are identified as starburst galaxies with strong [O III] lines of LOIII ∼ 1042.6–1044.2 erg s−1 and have stellar masses of M* ∼ 109.0–1010.6 Me and star formation rates of ∼10–210 Me yr−1 . Our results show that 24% of our sample galaxies are dusty with AV > 1 mag and EW([O III])rest ∼ 70–500 Å, which are often missed in optically selected [O III] ELG samples.en_US
