NIR Spectroscopy of Star-Forming Galaxies at z similar to 1.4 with Subaru/FMOS: The Mass-Metallicity Relation

Abstract:

We present near-infrared spectroscopic observations of star-forming galaxies at z ∼ 1.4 with FMOS on the Subaru Telescope. We observed K-band selected galaxies in the SXDS/UDS fields with K ≤ 23.9mag, 1.2 ≤ zph ≤ 1.6,M ≥ 10 9.5M, and expected F(Hα) ≥ 10 -16 erg s -1cm -2; 71 objects in the sample have significant detections of H?. For these objects, excluding possible AGNs, identified from the BPT diagram, gas-phase metallicities were obtained from the [N II] /Hα line ratio. The sample is spl...
