The emission line galaxy TV Reticuli [PDF]

open access: yesAstronomy & Astrophysics, 2006
TV Ret was classified as a cataclysmic variable due to an outburst observed in 1977. We intended to confirm this classification and derive some basic properties of the system. Low resolution optical spectra were obtained for a spectral classification of the object. We find that the object is not a cataclysmic variable but an emission line galaxy with a

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

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 ...

Emission-Line Diagnostics for Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractI will give an overview of the emission-line diagnostics used for star-forming galaxies. I will review the UV, optical, and IR diagnostics that can be used to yield information about the ISM conditions, star-formation properties, and power sources in GRB hosts, both globally, and with spatially-resolved data.

A Search for Emission Line Galaxies at z = 6.5 [PDF]

open access: yes, 2006
We are carrying out a search for Lyα emitting galaxies at z = 6.5 employing slitless spectroscopy at the VLT. In our 43 arcmin2 field we find three isolated single emission lines with SEDs consistent with line emitting galaxies at z = 6.5.

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.

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.

Evolution of Emission Line Galaxies [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1995
This thesis compares two samples of emission line galaxies, selected on the basis of the strength of their O III and/or H-beta emission lines. The distant sample has been drawn from the 4-Shooter transit survey undertaken by Schmidt, Schneider and Gunn (1994, AJ, 107, 1245 and references therein), and consists of 370 galaxies with emission line ...
