The University of Tokyo), Bunkyo-ku, Tokyo, Japan, We present follow-up optical DEIMOS/Keck-II spectra of in the order of 180 galaxies (median z in the order of 0.7) in the AKARI NEP-Deep field. The spectroscopic redshifts (z(sub spec)) agree well with photometric redshifts (z(sub phot)) at z less than 1, with mean absolute value of z approximately equal to 0.07, but the photometric redshifts are systematically too high at z greater than 1. One Seyfert 1.9 and one Seyfert 2 were identified from their emission lines, but no LINERs were found, in contrast to Kartaltepe et al. (2015), 84% of our objects are classified to be along the star-forming, HII sequence. At a given stellar mass, gas phase metallicities were found to be 0.1-0.2 dex lower than the local SDSS relation, but consistent with the relation found by Zahid et al. (2011) at z in the order of 0.8. Gas reddenings were derived from Balmer emission line ratios. In the majority of cases, the corresponding extinction at H alpha is in the order of 1 mag, typical of normal spiral galaxies. Star formation rates (SFRs) were estimated from the luminosities of either brackets O II brackets lambda 3727 or H alpha, and agreed reasonably (50% scatter). In galaxies with equivalent width EW(H alpha) of 10 angstroms or less, the broadband spectral energy distribution (SED) fitting significantly overestimates the SFR., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730026075, レポート番号: JAXA-SP-17-009E}, pages = {371--374}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {DEIMOS Spectroscopy of Star-Forming Galaxies in the AKARI North Ecliptic Pole-Deep Field}, volume = {JAXA-SP-17-009E}, year = {2018} }
