Large-Scale Structure Shocks at Low and High Redshifts
Steven Furlanetto, Abraham Loeb
Cosmological simulations show that, at the present time, a substantial fraction of the gas in the intergalactic medium (IGM) has been shock-heated to T>10^5 K. Here we develop an a…
Early Formation and Late Merging of the Giant Galaxies
Liang Gao, Abraham Loeb, P. J. E. Peebles +2
The most luminous galaxies in the present Universe are found at the centers of the most massive dark matter haloes, rich galaxy clusters. In the LCDM cosmology, such massive halo c…
Direct Feeding of the Black Hole at the Galactic Center with Radial Gas Streams from Close-In Stellar Winds
Abraham Loeb
We show that the recently-discovered orbits of massive stars with closest approach of ~10^3 Schwarzschild radii from SgrA*, allow winds from these stars to provide the required mas…
The Formation of the First Low-Mass Stars From Gas With Low Carbon and Oxygen Abundances
Volker Bromm, Abraham Loeb
The first stars in the Universe are predicted to have been much more massive than the Sun. Gravitational condensation accompanied by cooling of the primordial gas due to molecular…
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…
