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.

Multi-band constraints on the nature of emission line galaxies [PDF]

, 2012
Our aim is to explore the nature of emission line galaxies by combining high-resolution observations obtained in different bands to understand which objects are powered by an Active Galactic Nucleus(AGN).

SDSS-IV eBOSS emission-line galaxy pilot survey [PDF]

Astronomy & Astrophysics, 2016
The Sloan Digital Sky Survey IV extended Baryonic Oscillation Spectroscopic Survey (SDSS-IV/eBOSS) will observe 195,000 emission-line galaxies (ELGs) to measure the Baryonic Acoustic Oscillation standard ruler (BAO) at redshift 0.9. To test different ELG selection algorithms, 9,000 spectra were observed with the SDSS spectrograph as a pilot survey ...

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 ...

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 ...

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, 2016
Abstract We present basic properties of ∼3300 emission line galaxies detected by the FastSound survey, which are mostly Hα emitters at z ∼ 1.2–1.5 in the total area of about 20 deg2, with the Hα flux sensitivity limit of ∼1.6 × 10−16 erg cm−2 s−1 at 4.5 σ.

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.

Evolution of Emission Line Galaxies [PDF]

Publications 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 ...
