Cosmology at low frequencies: The 21 cm transition and the high-redshift Universe
TL;DR: In this article, the physics of the 21 cm transition were reviewed, focusing on processes relevant at high redshifts, and the insights to be gained from such observations were described.

Very High Gas Fractions and Extended Gas Reservoirs in z = 1.5 Disk Galaxies
Emanuele Daddi,Frédéric Bournaud,Fabian Walter,Helmut Dannerbauer,Chris Carilli,Mark Dickinson,David Elbaz,Glenn Morrison,Dominik A. Riechers,Masato Onodera,F. Salmi,Melanie Krips,Daniel Stern +12 more
TL;DR: In this article, the authors present evidence for very high gas fractions and extended molecular gas reservoirs in normal, near-infrared selected (BzK) galaxies at z~1.5, based on multi-configuration CO[2-1] observations obtained at the IRAM PdBI.

Lyman Break Galaxies at Redshift z ~ 3: Survey Description and Full Data Set*
Charles C. Steidel,Kurt L. Adelberger,Alice E. Shapley,Max Pettini,Mark Dickinson,Mauro Giavalisco +5 more
TL;DR: In this article, the authors present the basic data for a large ground-based spectroscopic survey for z ~ 3 Lyman break galaxies (LBGs), photometrically selected using rest-UV colors from very deep images in 17 high Galactic latitude fields.

DAMPED LYα SYSTEMS
TL;DR: In this paper, the H I and metal content of the gas and independent evidence for star formation in damped Lyα systems are discussed. But the authors focus on critical properties such as the HI and metal contents of the gases and do not consider the other properties, such as dust content, molecular content, ionized-gas content, gas kinematics and galaxy identifications.

The lyman alpha forest in the spectra of quasistellar objects
TL;DR: In this article, a cosmological hydro-simulations based or hierarchical structure formation models has led to important insights into the physical structures giving rise to the Lyman alpha (Ly alpha) forest.
