The Subaru FMOS Galaxy Redshift Survey ( FastSound ) . III . The mass - metallicity
We present the results from a large near-infrared spectroscopic survey with Subaru/FMOS (FastSound) consisting of ∼ 4,000 galaxies at z ∼ 1.4 with significant Hα detection. We measure the gas-phase metallicity from the [N II]λ6583/Hα emission line ratio of the composite spectra in various stellar mass and star-formation rate bins. The resulting mass-metallicity relation generally agrees with pr...
متن کاملThe Deep2 Galaxy Redshift Survey: Redshift Identification of Single-line Emission Galaxies
We present two methods for determining spectroscopic redshifts of galaxies in the deep2 survey which display only one identifiable feature, an emission line, in the observed spectrum (“single-line galaxies”). First, we assume each single line is one of the four brightest lines accessible to deep2: Hα, [O iii] λ5007, Hβ, or [O ii] λ3727. Then, we supplement spectral information with BRI photomet...
متن کاملProbing the Origin of the Cosmic Acceleration with the Subaru/FMOS Cosmological Redshift Survey
We propose the first large-scale cosmological redshift survey of the z > 1 Universe using the newly commissioned FMOS wide-field spectrograph in order to test for predicted gravitational departures from General Relativity in the early Universe. Spectroscopic redshifts will be secured using the Hα emission line for 20,000 galaxies with 0.7 < z < 1.6 over 30 deg by the target selection method tha...
متن کاملThe DEEP 2 Galaxy Redshift Survey : Environments of Poststarburst Galaxies at z ∼ 0 . 1 and z ∼ 0 . 8
Poststarburst (also known as K+A) galaxies exhibit spectroscopic signatures indicating that their star formation was recently quenched; they are candidates for galaxies in transition from a star-forming phase to a passively-evolving phase. We have spectroscopically identified large samples of poststarburst galaxies both in the Sloan Digital Sky Survey (SDSS) at z ∼ 0.1 and in the DEEP2 Galaxy R...

Poststarburst galaxies exhibit spectroscopic signatures indicating that their star formation was recently quenched; they are candidates for galaxies in transition from a star-forming phase to a passively-evolving phase. We have spectroscopically identified large samples of poststarburst galaxies both in the SDSS survey at z ∼ 0.1 and in the DEEP2 survey at z ∼ 0.8, using a uniform and robust se...
