▪ Abstract The formation of the first stars and quasars marks the transformation of the universe from its smooth initial state to its clumpy current state. In popular cosmological models, the first sources of light began to form at a redshift z = 30 and reionized most of the hydrogen in the universe by z = 7. Current observations are at the threshold of probing the hydrogen reionization epoch. The study of high-redshift sources is likely to attract major attention in observational and theoretical cosmology over the next decade.

Evolution of the Ionizing Background and the Epoch of Reionization from the Spectra of z ∼ 6 Quasars (2001, background): “When and how the universe reionized is one of the fundamental questions of modern cosmology (for a complete review, see Barkana & Loeb 2001 and Loeb & Barkana 2001).”
Galaxy bimodality due to cold flows and shock heating (2004, background): “The UV from stars and AGNs ionizes most of the gas after z ∼ 10 (Bullock et al. 2000; Loeb & Barkana 2001), heats it to >∼ 104K, and prevents it from falling into haloes below the Jeans scale Vv ∼ 30 km s−1 (Gnedin 2000).”
The First Stars (2003, background): “…the big bang, when the CMB photons shifted into the infrared, and the formation of the first sources of light, the universe would have appeared completely dark to a human observer (see Barkana & Loeb 2001, Loeb & Barkana 2001, Miralda-Escudé 2003 for comprehensive reviews of this cosmic epoch).”

Foreground simulations for the LOFAR-epoch of reionization experiment (2008, background): “Recent years have witnessed a flurry of theoretical activities to predict reionization sources and their impact on the IGM (e.g. Barkana & Loeb 2001; Loeb & Barkana 2001; Ciardi, Ferrara & White 2003a; Ciardi, Stoehr & White 2003b; Bromm & Larson 2004; Iliev et al. 2007; Thomas & Zaroubi 2007;…”
Mass Loss: Its Effect on the Evolution and Fate of High-Mass Stars (2014, background): “…estimates of mass-loss rates and their scaling with metallicity can profoundly impact topics as remote as reionization of the universe and the interpretation of spectra from galaxies at the highest redshifts currently being detected (Fan et al. 2006, Loeb & Barkana 2001, Morales & Wyithe 2010).”

Gamma-Ray Bursts in the Swift Era (2007, methodology): “…the so-called “dark age” (from cosmic background radiation atz ∼ 1100 to the epoch when first quasars were formed aroundz ∼ 7) is still poorly known (Loeb & Barkana 2001 for a review), GRBs, as bright beacons in the deep Universe, would be the unique tool to illuminate the dark Universe and…”

METALLICITY-DEPENDENT QUENCHING OF STAR FORMATION AT HIGH REDSHIFT IN SMALL GALAXIES (2011, background): “Proposed mechanisms include photoionization by the UV background (see the review by Loeb & Barkana 2001), and stellar feedback by supernovae (Dekel & Silk 1986) or radiation pressure (Thompson et al. 2005; Murray et al. 2010; Hopkins et al. 2011).”
