KILOPARSEC-SCALE PROPERTIES OF EMISSION-LINE GALAXIES [PDF]
The Astrophysical Journal, 2014 We perform a detailed study of the resolved properties of emission-line galaxies at kiloparsec scales to investigate how small-scale and global properties of galaxies are related. We use a sample of 119 galaxies in the GOODS fields. The galaxies are selected to cover a wide range in morphologies over the redshift range 0.2 < z < 1.3.

Galaxy Evolution in a Pilot Survey up to z=1 and CDM Halos
Advances in Astronomy, 2011 We study spectral evolution of galaxies in a magnitude limited sample of 550 galaxies from z=1 down to z=0.3 on a pencil beam of ≈10′×10′. We concentrate on the large apparent cosmological structures along the line of sight, and we bin our individual ...

Evolution of the Mass–Metallicity Relation from Redshift z ≈ 8 to the Local Universe
The Astrophysical Journal, 2023 A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of this correlation can strongly constrain theories of galaxy evolution.

The emission line galaxy TV Reticuli [PDF]
Astronomy & 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

Line-strength indices and velocity dispersions for 148 early-type galaxies in different environments [PDF]
, 2002 We have derived high quality line-strength indices and velocity dispersions for a sample of 148 early-type galaxies in different environments. The wavelength region covered by the observations ($\lambda \simeq 4600$ to 6600 Å) includes the Lick/IDS ...

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies
Frontiers 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 ...

Broad-band study of the evolving emission-line properties of galaxies [PDF]
, 2018 This thesis describes a new approach to the study of high-redshift star-formation and its environments that can be applied to large high-redshift surveys.Instead of relying on spectroscopy or narrow-band photometry to study galaxy line emission in detail,

Emission-Line Diagnostics for Galaxies [PDF]
Proceedings 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]
, 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.
