The Subaru FMOS Galaxy Redshift Survey (FastSound). II. The Emission Line Catalog and Properties of Emission Line Galaxies [PDF]

Publications of the Astronomical Society of Japan, 2015
We present basic properties of $\sim$3,300 emission line galaxies detected by the FastSound survey, which are mostly H$\alpha$ emitters at $z \sim$ 1.2-1.5 in the total area of about 20 deg$^2$, with the H$\alpha$ flux sensitivity limit of $\sim 1.6 ...

Machine-learning Classifiers for Intermediate Redshift Emission-line Galaxies [PDF]

The Astrophysical Journal, 2019
Classification of intermediate redshift (z = 0.3–0.8) emission line galaxies as star-forming galaxies, composite galaxies, active galactic nuclei (AGNs), or low-ionization nuclear emission regions (LINERs) using optical spectra alone was impossible ...

Evolution of [OIII]5007 emission-line profiles in narrow emission-line galaxies [PDF]

The Astrophysical Journal, 2011
The AGN-host co-evolution issue is investigated here by focusing on the evolution of the [\ion{O}{3}]$\lambda5007$ emission-line profile. In order to simultaneously measure both [\ion{O}{3}] line profile and circumnuclear stellar population in individual

HST EMISSION LINE GALAXIES AT z ∼ 2: COMPARING PHYSICAL PROPERTIES OF LYMAN ALPHA AND OPTICAL EMISSION LINE SELECTED GALAXIES [PDF]

The Astrophysical Journal, 2015
We compare the physical and morphological properties of z ∼ 2 Lyα emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z ∼ 2 optical emission line selected galaxies (oELGs) identified via HST WFC3 infrared ...

Spectral Classification of Emission-Line Galaxies [PDF]

The Astrophysical Journal Supplement Series, 1986
A revised method of classification of narrow-line active galaxies and H II region-like galaxies is proposed. It involves the line ratios which take full advantage of the physical distinction between the two types of objects and minimize the effects of reddening correction and errors in the flux calibration.

The rich cluster of galaxies ABCG~85. IV. Emission line galaxies, luminosity function and dynamical properties [PDF]

, 1998
This paper is the fourth of a series dealing with the cluster of galaxies ABCG 85. Using our two extensive photometric and spectroscopic catalogues (with 4232 and 551 galaxies respectively), we discuss here three topics derived from optical data.

Target Selection and Validation of DESI Emission Line Galaxies [PDF]

Astronomical Journal, 2022
The Dark Energy Spectroscopic Instrument (DESI) will precisely constrain cosmic expansion and the growth of structure by collecting ∼40 million extragalactic redshifts across ∼80% of cosmic history and one-third of the sky. The Emission Line galaxy (ELG)

Chemical abundances in high-redshift galaxies: a powerful new emission line diagnostic [PDF]

, 2016
This Letter presents a new, remarkably simple diagnostic specifically designed to derive chemical abundances for high redshift galaxies. It uses only the Hα$\mathrm{H}\alpha$, [N ii] and [S ii] emission lines, which can usually be observed in a single ...

The DESI One-Percent survey: exploring the Halo Occupation Distribution of Emission Line Galaxies with AbacusSummit simulations [PDF]

Journal of Cosmology and Astroparticle Physics, 2023
The One-Percent survey of the Dark Energy Spectroscopic Instrument collected ∼ 270k emission line galaxies (ELGs) at 0.8 < z < 1.6. The high completeness of the sample allowed the clustering to be measured down to scales never probed before, 0.04 Mpc/h ...
