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 ...

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).

Cosmology with Galaxies at High Redshifts
1991Following 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.

Starburst Galaxies at High Redshift
1997The 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.

Dynamics of High Redshift galaxies
This thesis presents a study of the kinematics and chemical abundance distributions of massive star-forming galaxies (SFGs) during the 1.5 billion years after the Big Bang at redshifts ...openaire +1 more source
