Detecting the Earliest Galaxies Through Two New Sources of 21cm Fluctuations
Rennan Barkana, Abraham Loeb
The first galaxies that formed at a redshift ~20-30 emitted continuum photons with energies between the Lyman-alpha and Lyman limit wavelengths of hydrogen, to which the neutral un…

A Method for Separating the Physics from the Astrophysics of High-Redshift 21cm Fluctuations
Rennan Barkana, Abraham Loeb
Fluctuations in the 21cm brightness from cosmic hydrogen at redshifts z > 6 were sourced by the primordial density perturbations from inflation as well as by the radiation from gal…

Was the Universe Reionized at Redshift 10?
Abraham Loeb, Rennan Barkana, Lars Hernquist
Recently, Pello et al. (2004) claimed to have discovered a galaxy at a redshift z=10, and identified a feature in its spectrum with a hydrogen Lyman-alpha emission line. If this id…
