High Redshift Lyman Break Galaxies

2006
Two of the most outstanding issues in modern astrophysics are what reionized the Universe and how did the first objects form. Observations of galaxies selected through the Lyman-Break technique indicate that UV photon output at the end of reionization was dominated by relatively faint low mass galaxies and not AGN.

High Redshift Radio Galaxies

Annual Review of Astronomy and Astrophysics, 1993
High redshift galaxies that host powerful radio sources are examined. An overview is presented of the content of radio surveys: 3CR and 3CRR, 4C and 4C/USS, B2/1 Jy, MG, MRC/1Jy, Parkes/PSR, B3, and ESO Key-Project. Narrow-line radio galaxies in the visible and UV, the source of ionization and excitation of the emission lines, emission-line ...

CO in High Redshift Galaxies

1997
Study of molecular gas in distant galaxies during the last twenty years has followed the steady progress in mm wave receiver sensitivity. In 1975, CO was detected in M 82, NGC 253, and several other galaxies with redshifts of a few hundred kms−1 (Rickard et al. 1975; Solomon & de Zafra 1975).

Starburst Galaxies at High Redshift

1997
The properties of ultraluminous and hyperluminous galaxies are reviewed and it is argued that the majority of the far infrared radiation from these galaxies is powered by starbursts. The evidence that the starburst population is also seen in the sub-mJy radio source-counts is reviewed and a model for the source-counts from radio to X-rays is presented.

Cosmology with Galaxies at High Redshifts

1991
Following some remarks on the methodology of the classical cosmological tests, recent observations of galaxies at high redshift are examined to see whether they place any constraints on the cosmological models. It is concluded that, at least at present, they do not.
