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…
Three-Body Kick to a Bright Quasar out of Its Galaxy During a Merger
Loren Hoffman, Abraham Loeb
The quasar HE0450-2958 was recently discovered to reside ~7kpc away from a galaxy that was likely disturbed by a recent merger. The lack of a massive spheroid of stars around the q…
The Fate of Former Companions to Hypervelocity Stars Originating at the Galactic Center
Idan Ginsburg, Abraham Loeb
The hypervelocity star SDSS J090745.0+024507 in the halo of the Milky Way galaxy (Brown et al. 2005) most likely originated from the breakup of a binary star system by the central…
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…
Nonthermal THz to TeV Emission from Stellar Wind Shocks in the Galactic Center
Eliot Quataert, Abraham Loeb
The central parsec of the Galaxy contains dozens of massive stars with a cumulative mass loss rate of ~ 10^{-3} solar masses per year. Shocks among these stellar winds produce the…
Imprint of Inhomogeneous Reionization on the Power Spectrum of Galaxy Surveys at High Redshifts
Daniel Babich, Abraham Loeb
We consider the effects of inhomogeneous reionization on the distribution of galaxies at high redshifts. Modulation of the formation process of the ionizing sources by large scale…
