The Origin of [OII] in Post-Starburst and Red-Sequence Galaxies in High-Redshift Clusters [PDF]
, 2010 We present the first results from a near-IR spectroscopic campaign of the Cl1604 supercluster at z~0.9 and the cluster RX J1821.6+6827 at z~0.82 to investigate the nature of [OII] 3727A emission in cluster galaxies at high redshift. Of the 401 members in

Bayesian Redshift Classification of Emission-line Galaxies with Photometric Equivalent Widths [PDF]
, 2015 We present a Bayesian approach to the redshift classification of emission-line galaxies when only a single emission line is detected spectroscopically.

Compact radio sources and jet-driven AGN feedback in the early Universe: Constraints from integral-field spectroscopy [PDF]
, 2007 To investigate the impact of radio jets during the formation epoch of their massive host galaxies, we present an analysis of two massive, log(M_stel/ M_sun)~10.6 and 11.3, compact radio galaxies at z=3.5, TNJ0205+2242 and TNJ0121+1320.

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

A Catalog of 71 Coronal Line Galaxies in MaNGA: [Ne v] Is an Effective AGN Tracer
The Astrophysical Journal, 2023 Despite the importance of active galactic nuclei (AGNs) in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation and other effects (e.g., Baldwin–Phillips ...

Spectral classification of emission-line galaxies from the Sloan Digital Sky Survey. I. An improved classification for high redshift galaxies [PDF]
, 2009 We study the spectral classification of emission-line galaxies as star-forming galaxies or Active Galactic Nuclei (AGNs). From the Sloan Digital Sky Survey (SDSS) high quality data, we define an improved classification to be used for high redshift ...

THE NATURE OF EXTREME EMISSION LINE GALAXIES AT z = 1–2: KINEMATICS AND METALLICITIES FROM NEAR-INFRARED SPECTROSCOPY [PDF]
, 2014 We present near-infrared spectroscopy of a sample of 22 Extreme Emission Line Galaxies at redshifts 1.3 < z < 2.3, confirming that these are low-mass (M⋆ = 108–109 M☉) galaxies undergoing intense starburst episodes (M⋆/SFR ∼ 10–100 Myr).
