Signature of Galactic Outflows as Absorption-Free Gaps in the Ly-alpha Forest
Taotao Fang, Abraham Loeb, David Tytler +2
Powerful outflows from star-forming galaxies are expected to push away the neutral intergalactic medium (IGM) around those galaxies, and produce absorption-free gaps in the Ly-alph…
Apparent Deviations from Keplerian Acceleration for Stars Around the Supermassive Black Hole at the Galactic Center
Abraham Loeb
We show that the time-dependent Doppler effect should induce measureable deviations of the time history of the projected orbit of a star around the supermassive black hole in the G…
Observing the First Stars, One Star at a Time
Abraham Loeb
Gamma-Ray Bursts (GRBs) are believed to originate in compact remnants (black holes or neutron stars) of massive stars. Their high luminosities make them detectable out to the edge…
A method to infer the stellar population that dominated the UV background at the end of reionization
Michael R. Santos, Abraham Loeb
We present an observational test of the spectrum of the ionizing background at z~5; the test is sufficiently sensitive to determine whether Pop II or Pop III stars are the dominant…
Galactic Constraints on the Sources of Ultra-High Energy Cosmic Rays
Abraham Loeb, Eli Waxman
We show that if the sources of ultra-high energy cosmic rays (UHECRs) with energies E>10^{19}eV are associated with galaxies, then the production of UHECRs must occur in transient…
Element Diffusion During Cosmological Structure Formation
David Medvigy, Abraham Loeb
We consider element diffusion during the linear growth of structure in the intergalactic medium (IGM) before the redshift of reionization. The elements produced during big bang nuc…
