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 کاملFabry-Perot Survey of Emission-Line Galaxies
The recent results from a deep Fabry-Perot survey of nearby active and star-forming galaxies are presented. Line-emitting material is detected over two orders of magnitude in galactocentric radius, from the 100-pc scale of the active or starbursting nucleus out to several 10s of kpc, sometimes well beyond the optical confines of the host galaxies. The excitation and dynamical properties of the ...
متن کاملThe [ OII ] λ 3727 / H α Ratio of Emission Line Galaxies in the 2 dF Galaxy Redshift Survey
We investigate the systematic variation of the [OII]λ3727/Hα flux line ratio as a function of various galaxy properties, i.e., luminosity, metallicity, reddening, and excitation state, for a sample of 1 124 emission-line galaxies, with a mean redshift z ∼ 0.06, drawn from the Two Degree Field Galaxy Redshift Survey. The mean observed and extinction-corrected emission-line flux ratios agree well...
متن کاملNear-Infrared Emission Line Searches for High-Redshift Galaxies
In this article I review recent developments in near-infrared emission line searches for star-forming galaxies at high redshift. Using the J-, H& K-bands we can potentially chart the history of star formation over the range 1 < z < 5 using the prominent rest-optical nebular emission lines alone, filling in the “redshift desert” at z ∼ 1 − 3 where most common emission lines lie outside the optic...
