High-Redshift Metals. II. Probing Reionization Galaxies with Low-Ionization Absorption Lines at Redshift Six
TL;DR: In this article, a survey for low-ionization metal absorption line systems towards 17 QSOs at redshifts z_em=5.3 5.8-6.4 is presented.

TL;DR: In this article, the authors presented new and archival Hubble Space Telescope (HST) images of circumnuclear star-forming rings in barred spiral galaxies, and they found that nuclear rings in these galaxies are composed of large numbers of super star clusters similar to those found recently in other types of starburst systems.
The Effect of Bars on the Fueling of Star Formation and Nonstellar Activity in Galaxy Nuclei

TL;DR: In this article, the authors show that large-scale stellar bars can be highly effective in delivering gas to the central few hundred parsecs of a spiral galaxy, which may then initiate rapid star formation.
QSO Absorption Lines, Early Evolution of Galactic Halos and the Metagalactic UV Flux

TL;DR: In this paper, a large fraction of the baryonic content of the Universe seen at redshifts z ~ 3 was in the form of tenuous highly ionized clouds in the outer halos of galaxies.

QSO Absorption Lines and Cosmology
Wallace L. W. Sargent
- 01 Jan 1987
TL;DR: In this paper, the properties of different types of QSO absorption lines are briefly summarized and an overview of the potential applications of absorption lines in cosmology is given, as well as the uses of the lines for studies of the evolution of clustering in the Universe.
