The Physical Conditions of Emission-line Galaxies at Cosmic Dawn from JWST/NIRSpec Spectroscopy in the SMACS 0723 Early Release Observations

open access: yesThe Astrophysical Journal, 2023
We present rest-frame optical emission-line flux ratio measurements for five z > 5 galaxies observed by the James Webb Space Telescope Near-Infared Spectrograph (NIRSpec) in the SMACS 0723 Early Release Observations.

Neutral hydrogen gas, past and future star-formation in galaxies in and around the 'Sausage' merging galaxy cluster [PDF]

open access: yes, 2015
CIZA J2242.8+5301 ($z = 0.188$, nicknamed 'Sausage') is an extremely massive ($M_{200}\sim 2.0 \times 10^{15}M_\odot$ ), merging cluster with shock waves towards its outskirts, which was found to host numerous emission-line galaxies.

Quantifying correlations between galaxy emission lines and stellar continua [PDF]

open access: yes, 2016
We analyse the correlations between continuum properties and emission line equivalent widths of star-forming and active galaxies from the Sloan Digital Sky Survey.

EMISSION LINE GALAXIES IN CLUSTERS [PDF]

open access: yes, 2006
At the present epoch, clusters of galaxies are known to be a hostile environment for emission-line galaxies, which are more commonly found in low density regions outside of clusters. In contrast, going to higher redshifts the population of emission-line galaxies in clusters becomes progressively more conspicuous, and large numbers of star-forming late ...

A contribution to the selection of emission-line galaxies using narrow-band filters in the optical airglow windows [PDF]

open access: yes, 2007
Emission line galaxies are an invaluable tool for our understanding of the evolution of galaxies in the Universe. Imaging of deep fields with narrow-band filters allows not only the selection of these objects, but also to infer the line flux and the ...

On the Origin of [OII] Emission in Red Sequence and Post-starburst Galaxies

open access: yes, 2005
We investigate the emission-line properties of galaxies with red rest-frame colors using spectra from SDSS DR4. Emission lines are detected in more than half of the red galaxies.

Emission Lines in Star Forming Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1995
Magris et al. (1993, Proceedings of the ESO/OHP Workshop on Dwarf Galaxies, ed. G. Meylan) have combined the spectral evolution population synthesis code of Bruzual & Charlot (1993, ApJ 405, 538) with the multipurpose photoionization-shock code MAPPINGS (Binette et al.

Shards of SHARDS: emission line galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractSHARDS (Survey for High-z Absorption Red & Dead Sources; see Pérez-González et al. 2012) is an optical ultra-deep spectro-photometric survey with OSIRIS-GTC aimed at selecting and studying massive passively evolving galaxies at z=1.0–2.3 in GOODS-North.

Dwarf Galaxies Show Little ISM Evolution from z ∼ 1 to z ∼ 0: A Spectroscopic Study of Metallicity, Star Formation, and Electron Density

open access: yesThe Astrophysical Journal, 2023
We present gas-phase metallicity measurements for 583 emission line galaxies at 0.3 < z < 0.85, including 388 dwarf galaxies with $\mathrm{log}({M}_{\star }/{M}_{\odot })\lt 9.5$ , and explore the dependence of the metallicity on the stellar mass and ...
