Spectral Implications of Variability in GRB Fireballs
Ravi P. Pilla, Abraham Loeb
Cosmological -ray bursts originate from relativistic winds. Temporal fluctuations in the wind velocity can give rise to internal shocks which dissipate a significant fraction of…
Detection of the First Star Clusters With NGST
Zoltan Haiman, Abraham Loeb
We calculate the observable signatures of the first generation of stars at high redshift (5<z<100). To determine the cosmic star-formation history, we use an extension of the Press…
The First Stars and Quasars in the Universe
Abraham Loeb
The transition between the nearly smooth initial state of the Universe and its clumpy state today occurred during the epoch when the first stars and low-luminosity quasars formed.…
Constraints on Galaxy Evolution and the Cosmological Constant From Damped Ly-alpha Absorbers
Eric Woods, Abraham Loeb
We use the existing catalog of Damped Lyman-Alpha (DLA) systems to place constraints on the amount of evolution in the baryonic content of galaxies and on the value of the cosmolog…
Formation and Signatures of the First Stars
Zoltan Haiman, Abraham Loeb
We use a spherical hydrodynamics code to show that in cold dark matter cosmologies, the first stars form at z=50 through the direct collapse of gas in low-mass systems (approx 10^4…
