Light-cone anisotropy in 21cm fluctuations during the epoch of reionization
Rennan Barkana, Abraham Loeb
The delay in light travel time along the line of sight generates an anisotropy in the power spectrum of 21cm brightness fluctuations from the epoch of reionization. We show that wh…
Detecting Reionization in the Star Formation Histories of High-Redshift Galaxies
Rennan Barkana, Abraham Loeb
The reionization of cosmic hydrogen, left over from the big bang, increased its temperature to >~ 1.e4 K. This photo-heating resulted in an increase of the minimum mass of galaxies…
A Cosmic Relation between Extinction and Star Formation
Oren Zoran, Rennan Barkana, Rodger I. Thompson
We study the relation between the star formation intensity of galaxies and the extinction by dust of their emitted light. We employ a detailed statistical analysis of Hubble Deep F…
Separating out the Alcock-Paczynski Effect on 21cm Fluctuations
Rennan Barkana
We reconsider the Alcock-Paczynski effect on 21cm fluctuations from high redshift, focusing on the 21cm power spectrum. We show that at each accessible redshift both the angular di…
Probing the Epoch of Early Baryonic Infall Through 21cm Fluctuations
Rennan Barkana, Abraham Loeb
After cosmological recombination, the primordial hydrogen gas decoupled from the cosmic microwave background (CMB) and fell into the gravitational potential wells of the dark matte…
